density of concrete hollow blocks
Concrete masonry unit Wikipedia
Composition. Concrete blocks are made from cast concrete (e.g. Portland cement and aggregate, usually sand and fine gravel, for highdensity blocks).Lower density blocks may use industrial wastes, such as fly ash or bottom ash, as an aggregate. Recycled materials, such as postconsumer glass, slag cement, or recycled aggregate, are often used in the composition of the blocks.
