No. Parameter AAC Block(Fusion Blocks)  Clay | Red Bricks
1 Size (mm) 600 * 200 * 100 – 300 230 * 115 * 75
2 Precision in size Variation (+ /-) 1 mm Variation 5 – 15 mm(+/-)
3 Compressive Strength 3.5–5N/mm2(As per IS.:2185),

Part-3, Grade-||

2.5-3.5 N/mm2
4 Dry Density 550-650 kg/m3 (Oven dry) 1950 Kg/m3
5 Wet Density App. 800 Kg./m3 App. 2400 Kg./m3
6 Fire Resistance 2 to 6 Hour depending on thickness 2 Hours
7 Sound Reduction Index (dB) 45 for 200 mm thick wall 50db for 230 mm thick wall
8 Thermal Conductivity.

(W-m/K)

0.16 0.81
9 Quality Uniform  &  Consistent Normally Varies
10 Quantity of Cement Consumption per M3 wall with 1:6 0.5 bag of Cement 1.4 bag of Cement
11 Construction Time

per mason

Very  High due to bigger in  Size , light weight , less no of Joints Comparatively lower
12 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 sulfates etc. which results in Efflorescence
13 Energy Saving ~25% Reduction in Power consumption of A/C No  Saving
14 Contribution to carpet area 3 – 5 % No saving
15 Cost benefit Factor Depending upon project design, savings up to 20% in structural cost due to reduction of dead load No saving
16 Availability Anytime Shortage in Monsoon
17 Breakage Less than 3% Average 12 to 15%
18 Fitting & Chasing All kind of fittings and Chasing Possible All kind of fittings and Chasing Possible
19 Structural Cost  Steel Saving  Up to 15% No  Savings
