This article explores the differences between AAC blocks and bricks, including their key features, pros, and cons.
Difference Between AAC Blocks and Clay Bricks
|Clay bricks are made from clay (alumina), sand, lime, iron oxide, and magnesia.||AAC blocks are made from a mixture of fly ash, lime, cement, gypsum, and aeration agent.|
|Clay bricks are red and smaller than AAC blocks.||AAC blocks are gray and manufactured in a bigger size.|
|The top layer of soil is used for manufacturing bricks. Hence, it is not eco-friendly.||Fly ash used for manufacturing AAC blocks is a non-toxic waste product recovered from thermal power plants. Hence, AAC blocks are eco-friendly.|
|Clay bricks are heavy (2.5 to 7.5 kg). Therefore, they increase the dead load of the main structure.||AAC blocks are lighter than traditional bricks (3 to 4 kg), which reduces the dead load of the structure.|
|The dry density of red clay bricks varies between 1600 kg/m3 to 1920 kg/m3.||The dry density of red clay bricks varies between 451 kg/m3 to 1000 kg/m3.|
|The compressive strength of red clay bricks is in the range of 2.5 to 3.5 N/mm2.||AAC blocks offer a compressive strength of 3 to 4.5 N/mm2.|
|Clay bricks are less stable against earthquake forces.||AAC block bricks are more stable against earthquake forces in comparison to clay brick structures.|
|Brick construction is time-consuming due to smaller bricks and more joints.||AAC blocks achieve speedy construction due to their bigger size, low weight, and fewer joints.|
|A dense brick masonry wall structure provides good sound insulation properties.||The presence of air voids in AAC blocks and its lightweight structure provides good sound reduction compared to red bricks.|
|Clay bricks are not termite resistant as they are made from organic materials.||AAC blocks are made from inorganic and insect-resistant materials that prevent termite attacks.|
|The thermal conductivity of clay bricks varies between 6 to 1 W/mK.||The thermal conductivity of AAC blocks varies between 0.21 to 0.42 W/mK. Hence, more thermal-resistant blocks are obtained.|
Compared to traditional clay bricks, AAC blocks are an all-weather construction material that offer superior performance and durability.
