Cement & Concrete Applications
Cement and Concrete Basics. In its simplest form, concrete is a mixture of paste and aggregates. The paste, composed of portland cement and water, coats the surface of the fine and coarse aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

The value of x2 is the target air content of the mix design (i.e. x2 = 6.5 %). The value of y2 is the unit weight of the concrete stated in the mix design. This is determined by obtaining the summation of the design batch weights and dividing by the summation of design absolute volumes which will always be 27.00 ft3.

Flowable Fill Concrete - Properties, Uses, Benefits
Properties of Flowable Fill Concrete. It has high lump (nearly 9 inch) but the strength is low, commonly 100 PSI (0.7 Mpa) in 28 days. It has low cementitious mix, does not hydrate and it settles and dewaters. The less water does not equate to faster hardening and too little water will not allow proper settlement.
