Jan 19,  · Materials For Eco-Friendly Concrete E. STONE CRUSHER WASTES: Quarry Rock Dust can be defined as residue, after the extraction and processing of rocks to form fine particles. It can be used as an alternative replacement for sand in the concrete. It has sharp and angular particles, thus because of such causes a gain in strength due to better
