recycled concrete barite

Classification of concrete | BIS

Classic (ordinary) concrete with bulk density from 1900 kg/m3 to 2500 kg/m3 and; Heavy-weight concrete with bulk density of higher than 2500 kg/m3. High bulk density of concrete is achieved by using heavy-weight aggregates, such as barite, iron ore (magnetite, hematite and limonite), splinters or specially made balls of iron and steel.
