Aerated Autoclave Concrete blocks contain 80% air and therefore weigh only 1/3rd of a clay Brick. It is formed as a reaction of aluminum metal with blended proportion of lime, cement, gypsum & fly Ash. The hydrogen gas escapes from the reaction giving AAC bricks a strong honey-comb structure. Also termed fly ash blocks these are further cured in an autoclave under high pressure steam to give it desired strength. The production process of AAC blocks has to be very carefully monitored to insure a controlled consistency in the proportions and timing of all ingredients that are used in each batch so that the output is consistent.
As it is light weight that will help to save structural cost. AAC Block is a replacement of traditional red clay brick.
AAC blocks is widely accepted in a construction industry because of its below features:
Block weight is significantly lower than clay bricks of equivalent volume.This leads lower dead weight of the structure and hence lower requirement for steel and cement in building the structure.
- Cost saving in the execution:
Since Magicrete AAC blocks weigh almost 80% less than clay bricks, they significantly reduce the deadweight of the structure which can result in huge costs savings attributed to reduction of steel and cement use.
Magicrete AAC blocks have very high compressive strength and hence they are suitable for varied kind of structures including high-rise, hospitals, schools, independent homes, office buildings, manufacturing units etc. The AAC blocks’ compressive strength is in the range of 3.5-4N/m2
while that of clay bricks is around 2.5-3N/m2
