Recycled Aggregates - Portland Cement Association
The natural process of carbonation occurs in all concrete from the surface inward. In the process of crushing concrete to create recycled concrete aggregates, areas of the concrete that have not carbonated are exposed to atmospheric carbon dioxide. The LEED ® Green Building Rating System recognizes recycled concrete in its point system. Credit,
How Cement Is Made
Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden., This involves several stages. The first crushing reduces the rock to a maximum size of about 6 inches. The rock then goes to secondary crushers or hammer mills for reduction to about 3 inches or smaller., a process that saves fuel,
