Measuring the water absorption of recycled aggregates .

Standard methods for determining the water absorption of coarse natural aggregates,, are widely used even for RAs. All standards recommend the following steps: (a) saturate the material by soaking (usually for 24 h or more, at atmospheric pressure); (b) use a towel to remove the film of water covering the surface and weigh the saturated surface dry (SSD) mass; (c) measure the hydrostatic .

Goad said degradation is the hardest issue to deal with. "You have your best practices in place and try to produce the material with a certain amount of degradation built in," he said. "The less you move material, the less expense is in it." Degradation arises with marginal aggregates that break down after stockpiling, Buchanan said.

A concrete mixture ratio of 1 part cement, 3 parts sand, and 3 parts aggregate will produce a concrete mix of approximately 3000 psi. Mixing water with the cement, sand, and stone will form a paste that will bind the materials together until the mix hardens. The strength properties of the concrete are inversely proportional to the water/cement .
