A concrete block is primarily used as a building material in the construction of walls is sometimes called a concrete masonry unit (CMU). A concrete block is one of the several precast concrete products used in construction. In use, concrete blocks are stacked one at a time and held together with fresh concrete mortar to form the desired length and height of the wall. The raw materials of blocks commonly used to make concrete blocks is a mixture of powdered Portland cement, water, sand, and gravel.A typical concrete block weight partially replaced by there raw materials by waste products may decrease the cost and also reduce environmental pollution. Indonesia coal, waste iron dust, and granite waste are used. Coal is a partial replacement of cement, granite waste is fully replaced by gravel. cement is replaced by superfast cement. In those combination mix is automatically adjusted to compensate, the temperature, pressure and cycle times are all controlled and recorded manually to ensure that the blocks are cured. Properly in order to achieve their required strength.
