Cement is necessary, but the strength can still be retained when using wellgraded aggregates that cost significantly less. Aggregates make up 6080% of the volume of concrete and 7085% of the mass of concrete. Aggregate is also very important for strength, thermal and elastic properties of concrete, dimensional stability and volume stability.

Composition of cement. Introduction Portland cement gets its strength from chemical reactions between the cement and water. The process is known as is a complex process that is best understood by first understanding the chemical composition of cement.

How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rocklike mass known as concrete.

Chemical Properties of Cement. The raw materials for cement production are limestone (calcium), sand or clay (silicon), bauxite (aluminum) and iron ore, and may include shells, chalk, marl, shale, clay, blast furnace slag, slate. Chemical analysis of cement raw materials provides insight into the chemical properties of cement.
