Project Report on Aerated Concrete Blocks/Hollow Blocks
Aerated Concrete Blocks/Hollow Blocks
Concrete blocks for building houses were first made in Europe around 1850. The mass-production of concrete blocks underwent in step with the development of the cement industry chiefly in Western Countries around 1918. In the United States, the concrete blocks industry recorded a major development after the introduction of the vibration process as a new method of compaction around 1930. During the World War - II, the concrete block industry developed significantly in Europian countries and the United States. Japan introduced the latest type of block making machine in the past war era. Cavity type or Hollow blocks are mainly made of materials like sand, gravel, and cement. These are used to construct walls of houses and other structures with embeded steel re-inforcement. They are safe & have good durability in earthquake & fire prone areas. The existence of cavity in concrete blocks helps keep rooms cool in summer and warm in winter, thereby making human living comfortable. On the other hand, it also reduces the cost of construction. The manufacturing technique is quite simple and concrete block manufacture does not offer many difficulties. Since concrete blocks are heavy, it is advantageous to set-up concrete block making plants near its consumption point rather than transporting them to long distance for use. The major raw material should also be available in the neighbourhood of a concrete block plant.
