Comparision Between Brick And AAC Block

 
Parameter AAC Block Clay Bricks
Size Length  X  Height  X  Thickness 625mm x  250mm x 100 - 300 mm Length  x  Height  x  Thickness 230mm  x  115mm  x 75mm
Precision  in size Variation  1.5 mm ( + / - ) Variation  5 mm ( + / - )
Compressive  Strength 35 - 40 Kg / cm2 25-30 Kg / cm2
Dry  Density 550 - 650 kg / m3 ( Over dry ) 1950 kg / m3
Wet  Density Approx. 800 - 850 kg. Approx. 2400 kg.
Fire  Resistance 3 to 6 hour depending on thick. 2 hour
Sound  Reduction  index (dB) 45 for 200 mm thick wall 50 for 230 mm thick wall
Thermal  Conductivity   Approx.  0.16 -- 0.17 Approx. 0.81
Adapation to various  surface finishes All kind of finish like in brick work is possible Same
Mortar  Consumption 0.018 per m3 with 1:6 / 0.5 bag of cement 0.1 per m3 with 1:6 / 1.35 bag of cement
Construction  Time 30 Sq.m with Block only, more  area can be constructed if total prefab system is used i.e 50  %  time saving. 20 Sq.m with Brick others as  Conventional
Energy  Saving 32 % (App.) Air-condition load  both  both heating and cooling will come down no saving
Cost benefit factor Depending upon project,Dead load reduce then saving in structural cost. no saving
Contribution to carpet area 2 - 3 % no saving
Chemical Composition Sand used used app.60 % which reacts with (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
