The CMA lobbies for best-practice technical standards in the manufacture and appli ion of precast concrete and promotes its members and their products as trusted market leaders.
By 1905, an estimated 1,500 companies were manufacturing concrete blocks in the United States. These early blocks were usually cast by hand, and the average output was about 10 blocks per person per hour. Today, concrete block manufacturing is a highly automated process that can produce up to 2,000 blocks per hour.
Fig. 1 Placing Hollow Concrete Blocks 3. MANUFACTURING PROCESS Cement concrete blocks can be solid dense or hollow. Besides different sizes and designs can be given to the blocks. The blocks are made in the sizes of 12x8x4"; 12x8x3"; 12x8x6", etc. Firstly cement, stone chips, sand, etc are mixed in the ratio of 1:6 or 1:12.

Solid concrete blocks :- 1500 to 2000kg/m3 Hollow concrete blocks:- 1000 to 1500kg/m3 Compressive Strength: Solid concrete blocks :- >5 N/mm2 Hollow concrete blocks:- >2 to 4 N/mm2 Water Absorption:- <10 to 15% by weight
800000 Nos. of cement concrete hollow blocks of size 100X200X400 mm. At 75% utilisation of the capacity, productions of 600000 Nos. of blocks have been taken into consideration. Cement concrete hollow blocks are usually of the following three dimensions: 100X200X400 mm, 150X200X400 mm and 200X200X400 mm. Although
