بيت /characteristics of coarse aggregates used in cement
Reactive Powder Concrete (RPC) is an ultra highstrength and high ductility cementitious composite with advanced mechanical and physical properties. It consists of a special concrete where the microstructure is optimized by precise gradation of all particles in the mix to yield maximum density.

Aggregate is one of the building materials used to produce concrete and mortar. When cement is mixed only with fine aggregates it is called cement mortar. Masonry mortar is different from a simple cement mortar because it contains other ingredients as well. Concrete contains both fine and coarse aggregate. Aggregates add strength to concrete and [.]

Readymixed concrete consists of fine aggregates, coarse aggregates, cementitious binders and water. Sometimes, admixtures are used to modify the appearance, workability or physical properties of the concrete. Hardened readymixed concrete offers durability, strength, water tightness, and resistance to abrasion.
