India is witnessing an exponential rate of expansion in urban areas which includes construction of interesting projects both commercial and residential in infrastructural sectors. The functional demands of a good, efficient and robust structure depends upon the type of construction components it has been built of. In addition to the basic materials, projects built today also require secondary materials for several purposes like durability and waterproofing etc.
Also, property investment is at its peak these days. People have become smart while choosing the house of their dreams. With the modern amenities the builders provide, they also demand and prefer constructions that are robust and have a strong foundation. So let’s find out what goes into making your houses strong.
Construction practices and concrete design today are strength driven. However, much attention to durability issues is being given these days due to an escalation in the repair and replacement costs. This is the reason why we need to stress on giving durability to the construction practices in addition to the strength. Concrete comprises of aggregates of rocks and mixture of paste. When the constituents undergo a chemical reaction, the paste hardens, gaining strength to form a rock-like mass called concrete.
Cement is a fine mineral powder that is one of the chief ingredients in concrete. It is an economical and a high-quality construction material used in construction projects across the world. Mixed with water, cement transforms into a paste that binds and hardens when submerged in water. Cement has different properties depending upon its make because of composition and fineness of the powder. It’s made by grinding a mixture of limestone and clay and then heated to a temperature of almost 1450 degree Celsius.
It is a byproduct obtained from burning pulverized coal in electric power generating plants. It is that undesirable product of thermal power plants which is not effectively utilized. Presently, over 150 million tons of fly ash is generated in a year. Its storage and disposal cost a substantial unproductive expenditure to thermal power plants. It is also used as a chief material in blocks, bricks and PCC pavements. It has also used as a constituent in paving roads and also in fine mills.
Condensed Silica Fume is a by-product of Ferro-Silicon industry. It is presently an imported product which is easily available in the Indian market. Its particle size is very small, approximately 100 times smaller than the particle size of cement. It has the ability to occupy the voids between cement particles in a concrete mix which reduces the water demand. Therefore it contributes to a dense concrete which is known for its high durability. Condensed Silica Fume is usually used to make high-performance concrete of lower grades.
Mineral admixtures are the components that are fused into concrete by mixing it with cement either in the cement plant or in the batching plant. This enhances the life of the concrete structure in a cost-effective and an affordable way. This happened after the realization of the need for concrete structures with more durability which led to change and transformation in the composition of concrete. From being a product composed of a couple of materials like cement, water and aggregates to being a durable composition mixed with minerals, the concrete structures are stronger and robust.
Numerous products are available to prevent and repair corrosion damage. A corrosion inhibiting admixture prevents damaging expansion and cracking caused by the formation of rust during corrosion. There are penetrating sealants composed of silane and siloxane that penetrate into the structure, soak into the surface, create a barrier against water and chlorides. This would, in turn, protect and repair concrete from the corrosive effects of chloride. In addition to this, various concrete waterproofing materials eliminate the need for external waterproofing membranes that are usually used. This saves time, resources at the construction sites. Overall, these materials become an integral part of the concrete matrix and transform concrete into a water-resistant barrier.
A Corrosion inhibitor raises the level of chlorides which is necessary to initiate corrosion or
decrease the rate of corrosion after it has started or both. It doesn’t really prevent corrosion from happening, hence these are also known as corrosion retarders. About 3-4% Calcium Nitrate of cement in terms of weight is sufficient for protecting the reinforcement steel against corrosion.
Purchasing a house is not only a big but a one-time investment. It is therefore essential to know what goes into making your house because it is these materials that form the foundation of your dream house. We, at Omaxe use high-quality construction materials making sure that the ingredients withstand the test of time and weather. After all, your dreams are going to turn into reality. Make sure it is a strong one.
