Cement is one of the most popular construction material in the modern world.It is a water-based binder used to bind other building materials together. In absence of cement, lime with various admixtures was widely used as a natural material.
Cement has made the modern world possible. It enables the tallest skyscraper defining a skyline of metro, expressways & highways, bridges, tunnels, dams & canals, to schools, colleges & hospitals to your home. What love is to family so cement is to home.

Cement can be defined as a soft grey powder and a versatile binding chemical compound that has provided several options for construction in this modern age. It can be used to hold the parts (aggregate, sand, bricks etc.) together by simply adding water. Cement has different properties depending upon its structure.
Cement, when mixed with water, transforms into a paste that binds and hardens.

For detailed explanations, we can state that cement is a binding agent. When water is added to cement, chemical reaction in form of hydration takes place making it into paste alike which has high compressive strength, durability & resistance. When properly weighed and mixed with aggregates and water, cement can make concrete or mortar. It remains workable for a relatively long period of time. Vice-versa, after a specific time concrete gains proper compressive & flexural strength and maintains long-term structure stability.
Cement is a mixture of compounds consisting mainly of silicates and aluminates of calcium formed out of silica, calcium oxide, aluminum oxide and iron oxide. We can state that cement is a hydraulic material made by finely grinding clinker (produced by burning a mixture of iron, calcium, aluminium and silica containing materials) together with Gypsum and other additives such as slag, pozzolana and fly ash.
The most commonly used cement is known as Portland cement. However, with an advance of new research & technology and in a quest for conserving natural resources and reducing pollution now a days pozzolana cement is become more and more popular.
Though masonry structures were possible with lime, the roofs, large span structures and structure subjected to heavy loads have become possible because of reinforced cement concrete, which would not have been possible without cement.
