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.
Jul 09, 2019· Manufacturing process of Concrete blocks. A concrete block is one among several precast concrete products used in construction. They are primarily used in the construction of walls. Mixing, molding, curing and cubing are the four basic processes involved in the manufacture of cement. Stage 1 - Mixing:
Lightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates. Structural lightweight concrete has an in-place density (unit weight) on the order of 90 to 115 lb / ft³ (1440 to 1840 kg/m³).
Densities range from about 460 to 750 kg m-3; for comparison, medium density concrete blocks have a typical density range of 1350-1500 kg m-3 and dense concrete blocks a range of 2300-2500 kg m-3. Autoclaved aerated concrete blocks are excellent thermal insulators and are typically used to form the inner leaf of a cavity wall.
main ingredients in manufacturing solid concrete blocks are: 1) Cement 2) Fly ash 3) Crushed sand (0-3mm) 4) Aggregates (5-10mm) Typical mix design for solid concrete blocks is given below, Mix design for block grade –7.5 Mpa (target strength) O.P.C: 100 kg Fly ash: 40kg Aggregates (10mm) 250 kg
