The amount of energy required by plant to crush material LOS ANGELES VALUE The Los Angeles test is commonly used to evaluate the hardness of aggregates to find the suitability of aggregates for use in road construction. Therefore, the road aggregates should be hard enough to resist abrasion. UCS (UNIAXIAL COMPRESSIVE STRENGTH)

The concrete Slump Test was created to help consistently measure the concrete workability. The "workability" of the concrete is an important factor for those placing the concrete. A workable concrete mix properly flows and fills the form properly, leaving minimal voids at the form face and completely surrounding any rebar to create a bond.

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects.
