Constituents of Concrete: Constituents of concrete are basically mixture of aggregate and paste. Paste 30 to 40% - Portland cement 7% to 15% by Vol & Water 14% to 21% by Vol. Note: Higher the concrete grade, paste volume will be higher. Aggregates 60% to 70% - Coarse aggregates & Fine aggregates. Note:

The rate of drying during this stage is determined by the quality of the cement paste: low water-cement ratio cement paste offers more resistance to vapor diffusion than high water-cement ratio paste. Concrete made with a water-cement ratio, greater than approximately 0.65, will have a continuously connected capillary pore system.

These concretes now constitute a highly sophisticated family of materials. Portland cement itself is a complex material, manufactured by first burning an intimate mixture of limestone and clay or shale in a kiln at temperatures in the range of 1400°C-1500°C, and then intergrinding the resulting clinker with a small amount of gypsum.
