Nodules range in size from 1mm to 25mm or more and are composed mainly of calcium silicates, typically 70%80%. The strength of concrete is mainly due to the reaction of these calcium silicates with water.

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres ( in) to 25 millimetres ( in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

COMPONENTS OF CONCRETE Concrete is made up of two components, aggregates and paste. Aggregates are generally classi! ed into two groups, ! ne and coarse, and occupy about 60 to 80 percent of the volume of concrete. The paste is composed of cement, water, and entrained air and ordinarily constitutes 20 to 40 percent of the total volume.
