SmartBrix vs. Conventional Bricks
Particulars SmartBrix Regular Clay Bricks
Size (LxHxB) 600mm x 200mm x 75mm,
100mm, 150mm, 200mm &
230mm
225mm x 100mm x75mm
Structural Cost Steel Saving Upto 15% No Saving
Mortar Consumption / Cu.M with 1:6 0.5 bag of cement (due to flat, even surfaces & less no. of joints) 1.35 bag of cement (due to irregular surface and more no. of joints)
Breakage Less than 3% Upto 15%
Construction speed Speedy construction due to its big size, light weight & easy to cut in any size or shape Comparatively slow
Quality Uniform & Consistent Normally varies
Carpet Area More due to less thickness of walls Comparatively low
Availability Any time Shortage in monsoon
Energy Saving Approx. 30% reduction in airconditioned load No such savings
Chemical Composition Sand/Flyash used around 60 - 70% which reacts with Lime & Cement to form AAC Soil is used which contains many inorganic impurities like sulphates etc. resulting in efflorescence
Precision In Size Variation 1.00 (+/-) mm Variation 3.15 (+/-)
Compressive Strength 3.5-4.5N/mm2(As per IS:2185 part III) 2.5 - 3.0 N/mm2
Sound Reduction Index1(dB) 45 for 200 mm thick wall 50 for 230 mm thick wall
Thermal Conductivity.(Kw-m/C) 0.16 0.81
Cost benefit factor Savings up to 24% in structural cost due to reduction of dead load (Subject to project design) No such savings
Weight 550 to 600 kg/Cubic meter 1950 to 2000 kg/Cubic meter
