crushing of dry concrete

crushing of dry concrete

Recycled Concrete is Less Expensive. Many people search for affordable construction materials to use for their projects. Crushed concrete is much less expensive than the most affordable structural fillers, including new concrete. This is because the entire recycling process implies very low collection, transportation and processing fees

    Curing Concrete. Concrete will set in three days but the chemical reaction between water and cement continues much longer. If the water disappears through evaporation, the chemical reaction will stop. It is therefore very important to keep the concrete wet (damp) for at least 7 days. Premature drying out may also result in cracking due to shrinkage
