Hollow Concrete Blocks: All You Need to Know

They are the standard sized rectangular hollow blocks made of cast concrete of high or low density. For high-density blocks, Portland cement and aggregate, usually sand and fine gravel are used as a raw material. For low density blocks, industrial wastes, such as fly ash or bottom ash are used as the primary raw materials and are often called cinder blocks /breeze blocks in different parts of ...
