The usefulness of concrete does not end when it gets formed into a structure. Old concrete slabs may be reused in several construction projects, depending on the material's size and shape.
You may be asking why there’s a need to reuse concrete, considering that cement and other construction materials are readily available.
First, used materials usually cost less than new items, which could lead to lower project costs. A technique called rubblization – or crushing old concrete on the site intended for use – reduces transportation costs because there’s no need to haul in new concrete.
Second, reusing old concrete pieces reduces the amount of solid waste. This significantly lowers construction waste and garners the company additional points when seeking certification for the LEED® Green Building Rating System. Reusing old materials also allows you to help save the environment.
If you’re considering reusing old concrete, here are some tips on how to maximize this money-saving and environment-friendly alternative:

Old concrete materials pegged for reuse are crushed using heavy equipment. The crushed concrete is sifted through screens that segregate unusable debris and particles from the actual concrete pieces, which can be further classified according to the crushing degree. The coarse aggregates are usually removed, and the finer concrete particles are passed through several cleaning procedures before getting the usable powder.
Use these tips to find new uses for concrete. It may even help you cut down on your costs.
