Concrete Design & Production - Portland Cement
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 ...

How concrete is made - material, manufacture, making,
At the cement production factory, the proportions of the various raw materials that go into cement must be checked to achieve a consistent kiln feed, and samples of the mix are frequently examined using X-ray fluorescence analysis. The strength of concrete is probably the most important property that must be tested to comply with specifications
