Cement is the chief ingredient in cement paste – the binding agent in portland cement concrete (PCC) is a hydraulic cement that, when combined with water, hardens into a solid mass. Interspersed in an aggregate matrix it forms PCC. As a material, portland cement has been used for well over 175 years and, from an empirical perspective, its behavior is wellunderstood.
Portland Cement . Cement: is a material with adhesive and cohesive properties which make it capable of bonding minerals fragments into a compact whole. For constructional purposes, the meaning of the term "cement" is restricted to the bonding materials used with stones, sand, bricks, building stones, etc.

Concrete basically consists of Portland cement, water, and fine and coarse aggregates. A pozzolan material, such as fly ash, may be added to the concrete mix as a partial substitute for cement. The curing of the concrete is a chemical reaction of the Portland cement and water, which causes the concrete to shrink and crack.

The cement slurry, commonly formed by mixing Portland cement, water and assorted dry and liquid additives, is pumped into place and allowed to solidify (typically for 12 to 24 hours) before additional drilling activity can resume. The cement usually must reach a strength of 5000 psi [34,474 KPa] before drilling or perforating.
