Cement is a material used to bond mineral pieces (Sand, Gravel, Brick, Briquette, etc) whose primitive materials are limestone and clay. There is a definite need for water in order for the cement to fulfill this bonding property. Cement is the component that occupies the smallest volume in many concrete mixes; but it is the most important one among concrete components.
