COMPARISON OF AAC BLOCK AND RED BRICKS
Sr.No Parameters AAC Blocks Bricks
1 Saving in steel 15-20% No saving in steel
2 Quality Uniform Quality due to mass production in the factory
Non-Uniform Quality
3 Compressive strength 30-35 Kg/cm2 20-25 Kg/cm2
4 Cement Consumption Less consumption of Mortar due to flat surfaces Column & Beam size reduced and so less Concrete Required
More consumption of Cement due to uneven surfacesNO saving in Concrete
![Page 18: AERATED AUTOCLAVED CONCRETE Prepared by Ankit Patel SD 1110.](https://reader031.fdocuments.in/reader031/viewer/2022020714/56649e535503460f94b48fbf/html5/thumbnails/18.jpg)
5 Labor Required
Less labors required More labors required
6 Sizes available
Available in sizes of 3", 4", 5", 6" 8",9" thickness
Available in 4", 6", 8" & 9" thickness
7 Carpet area More Carpet area is available in same built-up area due to less widths of walling
Less carpet area available due to more width of walling
8 Construction time
Speedy construction due to its big size
Slow constructions due to small size
9 Chemical Composition
Fly ash used app. 60 % which reacts with binders(Lime & Cement) to form AAC which is an inert material
Soil is used which contains many inorganic impurities like sulphates etc which results in efflorescence
10 Energy saving
30 % (app.) i.e. Air-condition Load both heating and cooling will come down.
No Saving

11 Additional Properties
1. Light weight ( Density 650 Kg/m3).
2.Highly insulating ( K value: 0.16 W/(mK). Therefore saves 25% cost of installation and also recurring cost of Electrical charges.
0.81W/(mK)
3.Highly Fire -resistant and incombustible (4 Hrs for 150mm AAC Block
2 Hrs
4.Sound Absorption : Absorbency of airborne sound for 4" is 39-40 db. Helps to cut off sounds. Less sound pollution
