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. The crushed rock is combined with other ingredients such as iron ore or fly ash and ground, mixed, and fed to a cement kiln.

Eco-friendliness is another big benefit of crushed concrete. Using this material helps slow down the production of new concrete and also frees up space in landfills. It prevents demolished concrete from sitting around taking up space and puts it to good use. Depending on how you have it installed, it’s also rather permeable.

The National Ready Mixed Concrete Association says that, during production, each pound of concrete releases between 5 percent and 13 percent of its weight in carbon dioxide. Assuming the middle range of 10 percent, the carbon dioxide released in the construction of a mile of a single interstate lane is: 0.1 x 8.7 million = 0.87 million pounds of carbon dioxide.
