Cement is a material which is applied to the surface of solid objects to hold them firmly together. To be more precise, cement is a powder which, after mixing with water, becomes soft and pasty (which hardens after drying) and is used for gluing stones, bricks, blocks, etc. in construction. Cement can be defined as an adhesive that is able to connect pieces of masses of solids together to form a compact mass.
