Aggregates - Portland Cement Association

Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.

Moisture in Portland Cement Concrete

Portland cement concrete shrinks as it dries, and, if this shrinkage is restrained in any way, tensile stresses will develop in the concrete. If there is a moisture gradient in the concrete, the concrete will have a tendency to curl. The weight of the concrete tends to resist the curling in installations such as
