VACUUM DEWATERED CONCRETE FLOORING PDF

The low-income groups in developing countries are generally unable to access the housing market. Cost effective housing is a relative concept and has more to do with budgeting and seeks to reduce construction cost through better management, appropriate use of local materials, skills and technology but without sacrificing the performance and structure life. It should be noted that low cost housings are not houses which constructed by cheap building materials of substandard quality. A low cost house is designed and constructed as any other house with regard to foundation, structure and strength. In residential construction, shear walls are straight external walls that typically form a box which provides all of the lateral support for the building.

How long will an epoxy system last? The life of an epoxy flooring system is dependent upon a number of factors: - Type of flooring system - Amount and type of traffic - Exposure to chemicals - Cleaning procedures Q. Epoxy coating systems can fail for a number of reasons including: - Moisture vapour transmission - Poor preparation of surface Q.

What is the cost of Epoxy flooring? What is the cost of Epoxy Coating? Although epoxy flooring systems perform well in a number of environments, epoxies are not recommended for many facilities within the food and beverage industry.

What is the cost of PU Flooring? Can we Paint over existing Epoxy Paint? We can do Epoxy Paint over existing Epoxy Paint but the existing epoxy paint should be grinded to give a KEY to make the new paint stick to it better. What is Load Transfer Mechanism? In case of heavy load traffic, a Load Transfer mechanism is used. Load transfer devices prevent the uneven shifting of Concrete Slabs under heavy loads. Shifting can cause uneven slabs and breakdown of the joints.

Dowels, load plates, or slots can be embedded into the concrete to act as load transfer devices. These devices are laid perpendicular to the construction joint, extending into both slabs across the joint.

Their purpose is to distribute the load evenly between slabs thereby protecting the concrete along the joints. What are the reasons of concrete cracking? Concrete expands and contracts constantly with changes in the temperature, the moisture content of the air and due to drying of cement which results in shrinkage.

The movements result in stress that can cause cracks in the concrete and destabilization of the base. Uncontrolled cracking can cause an uneven surface, which is subject to increased wear over time and water seepage, which can damage the substrate.

What is the meaning of grouting? The definition of grouting is filling masonry joints or gaps with a coarse, thin cement or mortar mixture. Masonry projects that incorporate individual tiles or rocks into a pattern on floors, walls or other flat surfaces are typically finished off by grouting.

Grouting is the application where we utilize a mix of cement and sand along with other material such as epoxy to fill the spaces that may result during some construction operation. Grouting is mainly used for filling the spaces rather than to hold any main stresses. What is Injection Grouting? Injection Grouting is specially designed for arresting seepages and dampness using Cementitious grouting admixed with expanding grout admixture or cutting off gushing water of high pressure and speed using Polyurethane Grouting and retrofitting works by using Epoxy resin Grouts.

The grout material, when mixed with a certain amount of accelerator, will react with water or moisture and expand, to form a tough, closed-cell rubber that is essentially unaffected by corrosive environment.

Injection Grouting is used for filling up the cracking in structural members, bonding concrete and other members permanently. Developed using modern techniques, Injection Grouting materials possess the following features: Q. Types of Injection Grouting? Polyurethane Grouting - used for arresting active water leakages where the pressure is high c.

How to patch a Concrete Floor? Vacuum, then clean the area with water and a wire brush. Wipe clean. Press it into the corners and against the edges with a trowel. Now fill the patches completely, leaving some material mounded on top. Move it back and forth in a sawing motion. This will also push down the aggregate and make the final smoothing easier. Do this several times as the mix cures.

To burnish the surface very smooth, use a steel trowel shown on the final few passes. What are joint sealants? Joint Fillers and Sealants are hard, semi-rigid materials typically used to fill the construction joints in concrete floors.

Being flexible joint sealants expand and contract along with the concrete. Their main purpose is to prevent water, other liquids, and debris from entering the joint. They can also improve the appearance of a floor. What are Floor Hardeners? Floor hardeners provide a dense, tough surface capable of withstanding the abrasion and impact loading seen by floor slabs in a wide range of commercial, industrial and manufacturing facilities.

What are the Types of Floor Hardeners? There are two types of Floor Hardeners: - - Dry shake floor hardeners come in mineral aggregate and metallic varieties.

The selection of a dry shake hardener is dependent on the specific solution intended for the particular application. What are Dry Shake Floor Hardeners? Dry shake floor hardeners come in mineral aggregate and metallic varieties.

Dry shake hardeners provide 2 to 8 times the abrasion resistance of plain, cured concrete. Most manufacturers offer hardeners in a range of colours. What are Metallic Floor Hardeners? Metallic floor hardeners are formulated with graded, non-oxidizing or oxidizing metallic aggregate in a high strength cementations binder. Mineral hardeners contain a mixture of well graded, non-metallic aggregates, plasticizer and cement binder.

Both are recommended for use in either interior or exterior applications where a hard, long wearing, heavy duty floor is required. Metallic hardeners should not be applied to concrete with intentionally added chloride. Give an example of Non- Metallic Floor Hardeners? Earth Compactor? Our Earth Compactors are compact, light weight, self propelled machines having low amplitude, high forces and high frequency based on the principle of reciprocal pressure generation by frequency unidirectional impulse vibrator which causes the ramming and forward movement.

What is the alkathene paper which is used for VDF Flooring? Alkathene Sheets are manufactured from a "new generation" virgin low density polyethylene. It is used as underlay for the VDF Flooring works. Yes we can. However, the existing epoxy paint should be sanded to "rough" it up to make the new paint stick to it better.

Does vacuum dewatered concrete require curing? Yes, the vacuum dewatered concrete requires curing in order to gain its strength. The concrete is cured for 28 days. What is the Grade of Concrete? Grade of concrete is the index of the strength of concrete. Minimum grade of concrete used shall be M15 conforming to IS What is Water Cement Ratio?

The water—cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix and has an important influence on the quality of concrete produced. A lower water-cement ratio leads to higher strength and durability, but may make the mix more difficult to place. Placement difficulties can be resolved by using plasticizers or super-plasticizers.

Concrete hardens as a result of the chemical reaction between cement and water known as hydration, this produces heat and is called the heat of hydration. For every kilogram of cement about 0. This requires a water-cement ratio of i. But this adversely affects the strength of concrete. For higher-strength concrete, the required lower water: cement ratios is maintained using plasticizer to increase flowability.

Typical water-cement ratio varies from 0. What is Polished Concrete in Flooring? A polished concrete floor has a glossy, mirror-like finish. We provide vast design options for polished concrete. We can polish concrete in nearly any colour, creating patterns with saw cuts or embed aggregates into the concrete prior to polishing.

The reflectivity of the floor can also be controlled by using different levels of concrete polishing. Polished concrete is popular in commercial buildings because it is easy to maintain.

Maintaining polished floors requires dust mopping and occasional use of a cleaning product. Simply put, polishing concrete is similar to sanding wood. Heavy-duty polishing machines equipped with progressively finer grits of diamond-impregnated segments or disks akin to sandpaper are used to gradually grind down surfaces to the desired degree of shine and smoothness.

How to do the Polishing of Concrete? Initial Rough Grinding: The process begins with the use of coarse diamond segments bonded in a metallic matrix. These segments are coarse enough to remove minor pits, blemishes, stains, or light coatings from the floor in preparation for final smoothing.

Depending on the condition of the concrete, this initial rough grinding is generally a three- to four-step process. Fine Grinding: The next steps involve fine grinding of the concrete surface using diamond abrasives embedded in a plastic or resin matrix. Crews use ever-finer grits of polishing disks a process called lapping until the floor has the desired sheen.

Panels: Steel flats of 75 mm thickness, 6 m in length. Workers would wear gumboots and hand gloves during concreting Proper illumination to be provided during the work, if required. Do prepare the surface on the concrete floor by hacking at close intervals 50 to 70 mm center to center with bush hammer or with a chisel and hammer and then wash it thoroughly with water. This will roughen up the concrete surfaces and ensure a good bond is provided for the IPS concrete. The surface thus prepared should be uniform, clean and saturated with water for minimum of 4 hours before concreting. Laying Procedure: Fix the panels dividers as mentioned in the drawing in position for diagonally alternative panels. Top of the strip must match with the required slope and finished floor level.
