concrete blocks properties

concrete blocks are building blocks obtained from concrete. It is a building block the size of several bricks with a mass less than concrete, which is very convenient for construction. One such block with a size of 200 x 300 x 600 (one of the most popular sizes) can replace with clutch 13 - 15 conventional or silicate bricks.
