How Concrete Is Made Portland Cement Association
How concrete is made. in its simplest form, concrete is a mixture of paste and aggregates, or rocks. the paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. through a chemical reaction called hydration, the paste hardens and gains strength to form the rocklike mass known as concrete.
Can You Mix Portland Cement With Just Water
Basically concrete is stronger and more durable so it can be used for structural projects such as setting posts whereas mortar is used as a bonding agent for bricks, stones, etc. concrete is a mixture of water, cement, sand just like mortar. one of the concretes we sell is the quikrete fast setting concrete mix.
