Concrete Design Production - Portland Cement Association

Concrete Design Production. Concrete is a mixture of two components: aggregates and paste. The paste, comprised of cement and water, binds the aggregates (usually sand and gravel or crushed stone) into a rocklike mass as the paste hardens. A properly proportioned concrete mix possesses acceptable workability of the freshly mixed concrete and ...

Concrete Ingredients - archtoolbox

May 12, 2021  Concrete is made up of four main ingredients: water, Portland cement, aggregates, and air. The ratio of the ingredients changes the properties of the final product, which allows the engineer to design concrete that meets their specific needs. Admixtures are added to adjust the concrete mixture for specific performance criteria.
