AAC BLOCKS vs RED BRICKS

DIFFERENCE BETWEEN AAC BLOCKS VS RED BRICKS

DIFFERENCE	AAC BLOCKS	RED CLAY BRICKS
Raw Materials	Cement, Fly ash, Water, & Air Entraining Agents	Clay (Alumina), Sand, Lime, Iron Oxide & Magnesia
Also Called as	Autoclaved Aerated Concrete Blocks	Red Bricks, Chamber Bricks, Clay Wire-Cut Bricks, Table Mold Bricks
Color	Grey	Red
Weight	4” Blocks   9-9.5 Kg 6” Blocks  12.5-13 Kg 8” Blocks  14-14.5 Kg	3” Bricks  3-3.5 Kg 6” Blocks  4.5-5 Kg
Fire Resistance (For 8” Wall)	Up to 4 Hours	Around 2 hours
Water Penetration	AAC blocks absorb 10% of water max. By weight, making them ideal for any construction project.	Red clay bricks generally absorb a lot of water, thereby limiting their utilization.
Sound Insulation	AAC blocks offer about 42 dB making them a superior choice over red clay bricks.	Normal sound absorption
Thermal Insulation	AAC blocks offer excellent insulation to projects, which directly result in heating, ventilation, and air conditioning (HVAC) cost savings of close to 25-30%.	low thermal conductivity and reduction of density
Size	600mm x 200mm x (75 to 300)mm	Standard Size: 190mm x 190mm x 90mm Nominal Size: 200mm x 100mm x 100mm
Cost of Construction	1 cum costs Rs.4200	1 cum costs Rs.2440
Strength	Grade 1 = 4 N/mm2 Grade 2 = 3 N/mm2	2.5 - 3 N/mm2
Uniform	They are relatively uniform in size	They are less uniform in size and texture
Load Carrying Capacity	Less when compared to Bricks	More when compared to AAC Blocks
No. of Blocks/Bricks per square meter	8 Number of Blocks	43 Numbers of Bricks
Prices of Blocks /Bricks per square meter	Rs.444	Rs.344
Range of Application	Suitable for Non-Load Bearing or RCC Structure	Suitable for Both Load Bearing & Non-Load Bearing Structure
Availability	Factory setup cost is high. So, Availability is a concern	Available locally in all cities and villages areas
Earthquake resistance	AAC blocks resist seismic activity, making them ideal for a wider range of projects across all regions.	Red Bricks are not ideal for all range of projects
Storage	AAC blocks are readily available across seasons, and do not require special storage on-site.	For red clay bricks, the monsoon season poses a significant challenge requiring special storage and handling.
Thermal Insulation	AAC blocks offer excellent insulation to projects	Red bricks less thermal insulation to projects
Appearance	·         These are generally grey in color with large sizes.	·         As the name suggests, these are red in color and comparatively smaller in sizes.
