SINUS ARMOUR JOINTS

sinus joints 1 Concrete Grade slabs are subjected to a lot of internal and external pressures with the maximum harm caused to the edge of the plates at joint location. If floor joints are faulty it will affect the horizontal and vertical movements of the floor which may lead to stress cracks as being exposed to heavy traffic movement and immense earth pressure. 
 

 Sinus-shaped armour joints allow smooth & jerk-free movement of MHE and forklifts over the construction joints and allow proper load transfer between floor slabs. It is because if it’s special shape which is not straight like conventional it classic shaped joints. They not only help in proper load transfer between slabs but also ensure longevity of the floor.

At BGSB, we use the best quality Sinus-shaped armour joints essentially required for constructing sturdy and seamless concrete floors.

Delamination in Concrete Floors

unnamed Hearing a hollow sound in your concrete floor? Or while tapping your floor, you discover more such empty, loud rings?Well, your concrete floor could be facing the common yet serious problem of delamination. A problem that’s audible even before it becomes visible.

Delamination is the detachment of a surface layer (top wear layer) due to the various technical reasons, including but not limited the ill-timing of hardener broadcasting, mix design issues or final trowel finishing process, which must only be started at an appropriate stage while the concrete is still green.

It is troweling that compresses and lessens the penetration of the surface layer of the concrete floor. If it’s done ahead of time, bleed water or air can be trapped below the cemented surface layer forming blisters that delaminate the surface.From our pouring experience of over a decade, we suggest to tackle such problem with a few noteworthy points that helped us overcome this situation and counter it successfully:

Crazing

crazing Crazing, a network pattern of fine cracks that do not penetrate much below the surface, is caused by minor surface shrinkage.

Crazing cracks are very fine and barely visible except when the concrete is drying after the surface has been wet. The cracks encompass small concrete areas less than 50 mm (2 in.) in dimension, forming a chicken-wire pattern. The term “map cracking” is often used to refer to cracks that are similar to crazing cracks only more visible and surrounding larger areas of concrete. Although crazing cracks may be unsightly and can collect dirt, crazing is not structurally serious and does not ordinarily indicate the start of future deterioration.

When concrete is just beginning to gain strength, the climatic conditions, particularly the relative humidity during the drying period in a wetting and drying cycle, are an important cause of crazing. Low humidity, high air temperature, hot sun, or drying wind, either separately or in any combination, can cause rapid surface drying that encourages crazing. A surface into which dry cement has been cast to hasten drying and finishing will be more subject to crazing. The conditions that contribute to dusting, as described below, also will increase the tendency to craze.

To prevent crazing, curing procedures should begin early, within minutes after final finishing when weather conditions warrant. When the temperature is high and the sun is out, some method of curing with water should be used, since this will stop rapid drying and lower the surface temperature. The concrete should be protected against rapid changes in temperature and moisture wherever feasible.

Concrete Polishing Benefits

From ordinary concrete floors, you can make a very interesting, inexpensive and durable flooring that holds permanently by concrete polishing . Even when renovating the floor, sanding and polishing can be a way of repairing a concrete floor in need of renovation.

Polish Concrete Floor

Concrete Polishing Benefits In commercial buildings, exposed concrete is often planned from the outset as a very durable and durable floor covering. Another floor covering is not necessary.During production, care is also taken to ensure that the surface is a bit smoother.

An ordinary concrete floor can also be used as a floor covering, if you grind it first, and then polished to shine. Of fair-faced concrete then distinguishes him only the "ordinary" optics.

Ground concrete floor as a stylistic device

When it comes to obtaining the most discreet and deliberately sober-looking floor covering, a sanded concrete floor is very suitable. In the interior, this can also be a ground screed.The floor is then very resistant to abrasion, has an interesting, but very subtle look due to the not quite uniform surface, and does not require baseboards.

Preventing Concrete Cracks

Preventing Concrete Cracks “WHY CONCRETE CRACK”

Poorly compacted or prepared sub-grade:

Excavations beneath the slabthat are not to be filled with concrete (usually plumbing or other mechanical trenches) should be brought back to grade in compacted lifts. This means a 24" (60 cm) trench would be back filled 6" (15 cm) at a time, each "lift" being mechanically vibrated so it is left compact. If these excavations are not compacted when backfilled, this loose soil will settle over time leaving the concrete over that area with no earth under it. This becomes a prime place for concrete to settle and crack.

Excess water in the mix:

Concrete requires very little water to hydrate properly.Typically concrete flat work is poured with toomuch water. For every pound (or kilogram or any unit of weight of cement, about 0.25 pounds (or 0.25 kg or corresponding unit) of water is needed to fully complete the hydration reactions. This requires a water-cement ratio of 1:4often given as a proportion: 0.25. However, a mix with a w/cratio of 0.25 may not mix thoroughly, and may not flow wellenough to be placed, so more water is used than is technically necessary to react with the cement. More typical water-cement ratios of 0.4 to 0.6 are used.

Concrete Joint types

Concrete Joint types

  • Freshly placed concrete is always prone to cracking off inside corners.
  • Spacing Recommendations no more that 2-3 times the size in inches
  • 4 inch thick slab need joints that are 8-12 feet on center
  • 2” slab = 4 to 6 foot joints
  • 5 cm slab = 2 meter squared joints
  • 4” slab = 8 to 12 foot joints
  • 10 cm, slab = 3.5 meter squared joints
  • 6” slab = 12 to 18 foot joints
  • 15 cm slab = 5 meters squared joints

What is the difference between a construction joint, isolation joint and control joints?

CONSTRUCTION JOINT

Joints in concrete pavement are created by forms to end one concrete pour and start another. If a pour is too large to cast at one time, workers set forms to complete the pour and then remove them to join the next placement to the old one. The cleanest way I have ever seen a construction joint placed is by using a small edger (the smallest you can find) on the first pour. This edger will be used to create a slightly rounded edge on the exterior formwork of the slab. From there your next pour will be finished to the existing height of the first pour and not edged. The next morning come back and use a framing chalk line to mark a straight line on the construction joint and saw cut the joint open. This will look like the two slabs were poured at the same time and saw cut later.

Concrete Curing Options

concrete curing option 1. Water Cure

  • Flooded
  • Ponded
  • Mist Sprayed

Water curing is the most effective method for curing concrete. Not the best option for Decorative Concrete work as thismethod is prone to efflorescence causing discoloration. Works well for standard gray concrete, or concrete that will be usedfor polished surfaces.

2. Water Retention Methods

  • Sand
  • Canvas
  • Burlap
  • Straw

Keeping the above stated options continuously wet or damp during the curing period will allow concrete to fully hydrate. Not the best option for Decorative Concrete work as this method is prone toefflorescence causing discoloration. Works well for standard grayconcrete, or concrete that will be used for polished surfaces.

Concrete Polishing

Concrete Polishing : Best way to treat concrete surfaces.

'Polished concrete eliminates the need for continually replacing your flooring, making it a value for money proposition' says Parmeet Bhalla Director, BGSB Concrete Solutions Pvt Ltd

Concrete polishing is steadily becoming the preferred choice of those looking for the ultimate no-wax/ epoxy flooring material. Thanks to recent advances in polishing equipment and techniques, concrete floors, both old and new, are attaining high-gloss finish that never needs waxes or coatings. The superior durability and performance of concrete mean that it is not surprising that an increasing number of retail, warehouse, and office facilities are opting for polished concrete flooring.Almost any concrete slab can be polished, regardless of its age. Moreover, no special acid agents are required in order to prepare the surface. The initial preparation consists of 5 or more steps of surface grinding. This is done in order to achieve a dense surface. Polishing with resin diamond grids subsequently follows this procedure. Additionally, based on specific requirements, lithium based floor hardeners and penetrating surface densifiers are also used for arriving at the right sheen.

8 Factors That Cause Cracks In The Concrete

The concrete is essentially a cheap material, easy to maintain and durable when applied correctly in buildings, floors or coating. The material is the result of a mixture of cement, sand, water, and gravel, therefore, although resistant, it is usually subject to the appearance of cracks and cracks, which need to be repaired.

1- Incorrect Preparation

Each type of concrete should be prepared with the correct proportions of the materials: cement, sand, water, and stone crushed stone. Any measurement error can cause the concrete to undergo environmental and structural influences, leading to cracks and cracks - as well as being extremely dangerous especially when used in supporting structures such as pillars and bases.

For countertops, for example, the recipe recommended by experts is 50 kilos of cement, 8 ½ cans of sand, 11 ½ cans of stone and two cans of water - where the can should measure 18 liters.

How To Lay A Concrete Floor

Due to the fact that concrete floors are capable of withstanding significant loads, their application area is quite large. This type of floor is ideal for industrial facilities (factories, factories, warehouses, vegetable stores, offices, supermarkets, etc.).Also, often a concrete floor is poured into sheds, garages and other economic buildings. The most common is a polished concrete floor, but, for example, in the pig sector demand for slotted concrete floors. If you decide to do it yourself, you just need to carefully study the recommendations on how to properly lay the concrete floor, so that the surface is even, firm and resistant to cracking.

Advice: When starting concrete flooring, follow these recommendations:

If the floor will experience increased loads, then it is necessary to pre-lay the reinforcing frame. For reinforced concrete mesh with insignificant loads; for the device of the concrete floor it is necessary to use cement of mark not lower than M300.  Note! After the ramming process, the thickness of the concrete floor should be approximately 12 cm.

Importance Of Concrete Warehouse Flooring

Concrete floors are most in demand for equipping warehouses, regardless of whether the floor is being filled or the concrete layer will be finished. Concrete Warehouse Floors are one of the most important elements of a warehouse complex. They experience huge loads, a hard abrasive, mechanical, impact, constantly subject to the influence of chemical elements and temperature changes.

Why Warehouse Flooring Is Important
The warehouse floors are subject to increased requirements. Warehouse Flooring should be:

  • Resistant to abrasive abrasion : one of the main factors in the destruction of storage floors.
  • Resistant to Mechanical Stress: Warehouses often move transport, so the floor covering must have improved characteristics to withstand shear stresses. The same property should have floors in the garages.
  • Resistant to Impact: Heavy objects can fall on the floors. In this case, the monolithic coating should not be violated.
  • Possessing Chemical Resistance: Warehouse floors in the chemical industry are subject to the influence of aggressive liquids: solvents, paints, acids, etc.
    Insensitive to temperature changes: Industrial floors in factories, where elevated temperatures are used with frequent changes, are often violated prematurely. Particularly relevant, additional reinforcement of the base is for storage facilities with access to the street, freezers and refrigerators;
  • Impermeable to Liquids: To ensure that the floors in warehouses are not adversely affected by frequent wet cleanings, and the soil through which no environmentally hazardous substance has penetrated, the coating must not allow liquid to pass through.
  • Non-slippery: Both in dry and wet conditions, to ensure the safety of transport and pedestrians.
    Fireproof and durable : To ensure the safety of the goods or raw materials stored in the storage room.This is why when installing industrial floors for a warehouse, it is necessary to take into account operational requirements, load distribution parameters, and other factors. Do not miss any of these nuances and find the best option for the device flooring will help specialists of the company Prom-Floor.

How To Polish Concrete Floor By Hand - Step By Step

The rough concrete surface becomes dirty and breaks down much faster than polished. In addition, from an aesthetic point of view, polished concrete looks much more attractive. Polishing concrete can be done by own hands, which will greatly improve its aesthetic qualities and performance. After grinding, the floor can be laid on concrete or its surface can remain open.

Preparatory stages of work

To obtain the desired result, it is necessary to perform surface preparation (milling) and grinding. The main tasks of milling are cutting off the hillocks on the surface, removing the influxes, opening the pores. Also during this process, grinding of the upper layer is carried out.

Types of Industrial Flooring

Industrial Flooring is in great demand and we can broadly classify these floors based on material used. Here are various types ofIndustrial Floors.

Concrete floors

This is one of the most common types of Industrial flooring , which often serves as a base for the functionality of all other types of coatings. It is the strength, evenness, and reliability of concrete floors that determine the operational characteristics of future floors, made on their basis.

Paint floors

The surface layer is a thin layer coating with a thickness of about 0.3 mm, which protects the concrete, metal or cement-polymer floor from the effects of water, chemically aggressive media and dusting. The polymer coating of the surface layer is excellent for decorating floors, as well as for compliance with hygienic and sanitary standards. However, such floors are quite sensitive to high mechanical loads, in addition, the quality of the base (strength, evenness, and absence of cracks) is of particular importance, since it determines the operational properties of the floor as a whole.

Concrete industrial flooring Using Laser Screed Technology


Laser concrete Floors

The Laser Screed Concrete Flooring guarantees inimitable quantitative and qualitative performance, as well as a considerable reduction in work time and costs. Through the automated system, laser screed machines ensure greater precision in the laying of the concrete, which takes place at the predetermined level, and a total uniformity of the final surface.

The optimization of the seasoning and compacting phase allows overcoming all the problems related to manual laying in terms of flatness, horizontality, reduction of joints and mechanical resistance.

Post-tensioned floors
The "post tension" is the most innovative solution in the field of industrial concrete flooring, a very high-performance procedure that provides for the replacement of the classic reinforcements with mono strand steel cables, treated and sheathed in concrete, and subsequently post-thesis through the use of hydraulic jacks. The result is monolithic floors with reduced thickness, without expansion joints and control, which ensure high flatness and a drastic reduction in maintenance costs, as well as a very high resistance to cracks and boats.

What Is industrial flooring

polished concrete3 To the question - what is the industrial flooring ? - the first thing is an industrial structure - a large object, implying its production features. But this does not mean that the industrial floor is used exclusively at industrial construction sites. In the term "industrial", the importance is not so much that the floor is located on an industrial site - in a shop, in a warehouse, etc., but that the floor is operated in a "hard" - "industrial" way.

Capital construction can be carried out in the form of new construction, expansion, technical re-equipment, reconstruction or modernization of the enterprise includes all branches of construction and is divided into industrial, civil, transport, military construction, etc. Modern industrial floors are used in construction in all departments of capital construction and reconstruction of premises.

Industrial flooring is significantly different from the construction of other types. When implementing these facilities, modern technologies are used, operational loads are taken into account, floors must satisfy all the requirements of technological processes, ensure a long service life, reliable operation.
