Concrete a mixture of aggregate and cement

• Concrete: a mixture of aggregate and cement – Aggregate: rocks, sand, slag, stones – Cement: binding agent • Masonry mortar: a mixture of cement, sand, and other additives • Cement binds the sand and coarse aggregate into a solid mass through chemical reactions, called hydration reactions, between cement and water.

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 rock-like mass known as concrete.

Any powder, salt, or oil that is on the surface of the rocks will change the bond it will form with the cement.

Can I Make Concrete with Just Sand and Cement?

Concrete is a mixture of Portland cement, water, sand, and stone. The stone element, also known as the aggregate, is why concrete cannot be made simply by mixing sand and cement. Sand is much too fine of an element to provide the compressive strength and durability that concrete needs.

The Difference Between Cement And Concrete

Concrete is a mixture of cement, water, and aggregates. Aggregates make up approximately 60-75% of the mixture and cement and water make up the rest. Aggregates are usually inert course materials like gravel, crushed stone, sand, or recycled concrete. The type of aggregate selected depends on the application of the concrete.
