Recycled Concrete Aggregate | Civil Engineering Forum

One form of recycled concrete aggregate is returned-to-plant concrete. This involves fresh concrete that has been returned to the batching plant, discharged from the transit mixer and left to harden. The hardened concrete is the crushed and sieved to produce RCA. RCA has seen use all around the world, particularly in North America and Europe.

Compressive strength of high strength concrete mix is usually greater than 6,000 pounds per square inch.. High strength concrete is made by lowering the water cement (W/C) ratio to 0.35 or lower. Often silica fume is added to prevent the formation of free calcium hydroxide crystals in the cement, which might reduce the strength at the cement aggregate bond.
