USEFUL PROPERTIES OF VSPL AAC BLOCKS

VSPL AAC Blocks has density ( Over Dry ) are between 551 to 650 Kg/Cum i.e., 1/3 than brick and 1/4 than concrete, hence maximum material can be accommodate in one truck, less requirement of trucks against conventional wall material, less movement of trucks hence less pollution, less use of natural resources, diesel, road and other infra structure’s.  Due to use of VSPL AAC Blocks in masonry economy in structural design which will reduce the depth of foundation, size of structural members, finally saving in the cost of cement , steel, course aggregate, fine Aggregates require for concrete, suitable for the structure on low bearing soil, marshy lands, it will useful for all types of residential/commercial/Industrial,Multi – Stored projects which will save the use of land horizontally suitable for using additional FSI/TDR on existing building/societies.

Applications of VSPL Auto Aerated Concrete (AAC)Products

VSPL AAC BLOCKS:

  • For the construction of partition, internal wall as external walls of residential, commercial, Industrial buildings, Malls, Multiplexes, Institutional Buildings, Hotel, Hospitals, various types of SEZ, Port, Factories, Apartments, Warehoused, and Godowns.
