cement Definition Composition Manufacture History
Concrete is a mixture of cement sand or other fine aggregate and a coarse aggregate that for most purposes is up to 19 to 25 mm (0.75 to 1 inch) in size but the coarse aggregate may also be as large as 150 mm (6 inches) when concrete is placed in large masses such as dams. Mortars are used for binding bricks blocks and stone in walls or as

Compressive Strength of Concrete Concrete Cubes What
· The strength of concrete is controlled by the proportioning of cement coarse and fine aggregates water and various admixtures. The ratio of the water to cement is the chief factor for determining concrete strength. The lower the water-cement ratio the higher is the compressive strength.
