WEIGHT

Lightweight bricks are also the important objective of this project. So, all the bricks were tested whether they are having less weight or not. All the bricks were weighed in a well-conditioned electronic weighing machine. The following are the weight of fibrous concrete bricks and padobe bricks.     

       Weight of fibrous concrete and padobe brick

Weight chart

The ordinary conventional bricks weight varies from 30 to 35 N. but the fibrous concrete and padobe bricks weight varies from 8 to 20 N. The maximum weight is less than 20N only. In this above proportion fly ash and rice husk ash based bricks are having 1/3 ^rd of the conventional brick weight only. Padobe and sand based bricks are having weight 2/3 ^rd of conventional brick weight only. So this bricks are light weight and it will also reduce total cost of construction due to the reduction in dead load
