Briefly describe how concrete is made and describe its beneficial properties.
What will be an ideal response?
?Concrete can be made by simple hand mixing methods or in large quantities at a computer controlled batching plant.Concreteis a solid, hard material produced by combining Portland cement, coarse and fine aggregates, and water in proper proportions. The mix is composed of paste and aggregates. The paste, composed of Portland cement and water, coats the surface of the fine and coarse aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.Concrete is strong and durable, long lasting and possesses plastic qualities for infinite formal possibilities. Its constituent ingredients are derived from a wide variety of naturally occurring materials that are readily available in most parts of the world.
