  • Better thermal insulation is provided.
  • It correctly absorbs sound and protects the interiors from noise pollution. Using concrete blocks offers extra hearth protection.
  • Protects valuable agricultural land that is considerably mined to produce clay bricks.
  • Individual portions can be manufactured to a large personalized measurement and shape, permitting for a rapid constructing cycle turnaround.

The following critical steps contain the manufacturing process:


According to the Indian Standard Code 2185 – Part 1 or in accordance with the required strength, the cloth proportion is taken.


Precise batching of the aspects and thorough mixing are required to attain a uniform mix. The procedure should proceed till the aspects are dispensed evenly.


Vibro compaction need to be used to compact the block and end to the proper measurement barring any damaged edges.


The blocks have to be stored persistently moist for at least 14 days whilst curing in a water tank or yard. The water in the immersion tank the place the blocks are curing have to be modified at least each 4 days.
