Concrete originated as a term from the Latin word “Concretus”. It represents a state of compactness and thickness. A balanced assortment of vital ingredients such as sand, water, Portland cement, crushed stone or gravel (it is commonly known as coarse aggregate) and other chemical properties ultimately result in shape of concrete. When it is blended with water and discharged into molds in fluid state, concrete can be transformed into any shape. It hardens progressively and finally turns into a very strong material which is no less than a stone. The way concrete hardens is called ‘Hydration’. In this entire process water is a reagent. It reacts with cement and helps it function like glue. Because of water the bonding of various components becomes faster. Concrete is a quintessential ingredient in long-lasting constructions such as pillars, roofs, poles, roads, highways, foundations, overpasses, bridges, parking infrastructures etc. the diagram given below will do the needful to present a ballpark figure of the ratio in which the components of concrete mix up.
