Comparison Between MAXCRETE AAC Block and Clay Brick

Parameter MAXCRETE AAC Block Clay Brick
Raw Materials Cement, sand, high quality lime, gypsum, aluminum powder Top fertile soil
Eco-Friendliness Pollution free Emissions Carbon dioxide (CO2), uses high energy, wastes agricultural land
Size in mm
(Length x Height x Width )
L x H: 600 mm x 200 mm
W: 100 mm -250 mm (Customized)
L X H: 241.3 mm x 69.85 mm
W: 114.3 mm (Non-customized)
Dry Density 550-850 Kg/m³ 1800-1950 Kg/m³
Fire Resistance 4 to 6 hours 2 hours
Sound Reduction Index 40-45 db 50 db
Thermal Conductivity 0.12- 0.18 W/m-k 0.81- 1.0 W/m-k
Mortar Consumption Requires less mortar due to flat and even surface & less number of joints. Requires more mortar due to irregular surface & more number of joints.
Structural cost Saving up to 20% in structural cost (subject to project design) No such savings
Ease of Working Can be directly cut or shaped/ sculptured as required Not possible
Breakage & Utilization Negligible breakage almost 100 % utilization is possible. On an average, 10 to 12% breakage happens on construction site, so 100% utilization is not possible
Maintenance Less due to its superior finish Comparatively higher
Labor Output Less labors are required More labors are required due to small size and lots of joints
Energy saving Low thermal conductivity helps in saving electricity costs 20-30% for heating and cooling of house No savings
Construction speed Very fast due to bigger size & lightweight Comparatively slower
Quality Uniform and Consistent Normally varies
Capillary Water Absorption Less (due to low density) More (due to High Density)
Carpet area More due to less thickness of walling material Comparatively low
