Brick are classified into three groups on the basis of their water absorption and strength. First Class Brick They have the compressive strength of 10 N/mm2. The water absorption should not be more than 15% of the self weight within 24 hours of immersion in water.The shape are proper and size are upto the standard. Second Class Brick They have the compressive strength of 7.5 N/mm2. The water absorption should not be more than 20% of the self weight within […]

Number of bricks required in wall depends upon the size of brick. Here I am taking Standard size of brick = 240mm*115mm*57mm as per NBC Assume the size of mortar as 10mm Size of brick with mortar = 250mm*125*67mm Volume of 1 brick = (240*115*57)/10003=1.573*10-3 m3 Volume of 1 brick with mortar= (250*125*67)/10003=2.093*10-3 m3 Volume of mortar = 2.093*10-3-1.573*10-3 m3=5.2*10-4 m3 No of bricks required in 1m3 wall without mortar= 1/1.573*10-3 =635.72 numbers No of bricks required in 1m3 wall with mortar = 1/2.093*10-3 =477.78 numbers […]
