The foundation defines the longevity of a building. The materials used in construction have an impact on the building. However, different types of cement are used for different things. Construction of reservoirs, marine structures, cooling towers, railway sleepers, industrial buildings, dams, bridges, flyovers, runways, or metro line, requires different grades of cement. The major categories of cement are Ordinary Portland Cement (OPC), Portland Pozzolana Cement (PPC), Portland Slag Cement (PSC).
