    • What''s the Difference Between Cement and Concrete?

      The paste, composed of cement and water, coats the surface of the fine (sand) and coarse aggregates (rocks) and binds them together into a rock-like mass known as concrete. Within this process lies the key to a remarkable trait of concrete: it''s plastic and can be molded or formed into any shape when newly mixed, strong and durable when hardened.

      Nearly all natural aggregates originate from bed rocks. There are three kinds of rocks, namely, igneous, sedimentary and metamorphic. In such, many properties of aggregate depend on the properties of the parent rock itself. Coarse aggregates are classified into two main groups: (i) single-size aggregate and (ii) graded aggregate.
