concrete reutilization
Reutilization of Waste Concrete Powder by Cement . The study is focused on the reutilization of the waste concrete powder, which is a by-product of recycling the waste concrete. This concrete powder is producted (about 30% in weight of original waste concrete) when the waste concrete is crushed and the aggregates are sieved away. More
