Ask for concrete with recycled aggregate
Reusing waste materials for aggregate conserves resources
Crushed concrete and fly ashFine particulates consisting primarily of silica, alumina, and iron that are collected from flue gases during coal combustion. Flyash is employed as a substitute for some of the portland cement used in the making of concrete, producing a denser, stronger, and slower-setting material while eliminating a portion of the energy-intensive cement required.
More info from coal-burning power plants are among the materials that can be recycled by using them as aggregate in concrete. For countertops and other interior concrete fixtures, a wide range of materials can be used to create decorative effects. Reusing materials reduces the environmental impact of mining and crushing stone for aggregate and keeps waste out of landfills.
