Ways to Recycle and Reuse Concrete

Concrete is recycled by using industrial crushing equipment with jaws and large impactors. After the concrete is broken up, it is usually run through a secondary impactor and is then screened to remove dirt and particles and to separate the large and small aggregate.

How concrete is made

Portland cement, the kind most often used in concrete, is made from a combination of a calcareous material (usually limestone) and of silica and alumina found as clay or shale. In lesser amounts, it can also contain iron oxide and magnesia. Aggregates, which comprise 75 percent of concrete by volume,

10 Advantages of Concrete as Construction Material

Oct 20, 2016The amount of energy required for production of concrete is low compared with steel. For plain cement concrete only 450–750 kWh/ton energy is required and that of reinforced concrete is 800–3200 kWh/ton. Production of structural steel demands 8000 kWh/ton or more to make which is almost 3-10 times the energy consumption. 5.
