What CRH concrete and aggregates are and how they work

CRH concrete and aggregates cover several materials. Aggregates include crushed stone, sand, and gravel. These are combined with cement and water to form ready-mix concrete, which hardens into a stone-like mass through hydration reactions in the cement paste Portland Cement Association, 02/06/2024.

Within CRH, aggregates and cement are supplied to ready-mix plants that batch specific concrete mixes for foundations, slabs, pavements, and structural elements.
