What is concrete - Concrete Defined - The Concrete Network
Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and Portland cement. Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates. This combination, or concrete mix, will be poured and harden into the durable material with which we are all familiar.

Boral Concrete | Boral
What is Concrete? Concrete is composed of aggregates (crushed rock and sand) bonded together with ‘cementitious’ binders (cement) and water, which then hardens over time once laid in place. Generally coarse gravel or crushed rocks from Boral Quarries, along with finer materials such as sand, provide the required aggregate component. Cement is sourced from Boral’s Cement business.
