clay bricks?
 Question Submitted By :: Civil-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
Advantages outweigh the disadvantages of using Fly Ash
Bricks over Clay Bricks.
Fly Ash Bricks Advantage:
1. Due to perfect size savings in cement mortar for making
the walls and plastering by 20-40%
2. Strength of supplied lot is similar.
3. Plaster of Paris, Putty can be applied directly without a
backing coat of plaster.
4. Lower water penetration to Clay Bricks.
5. High Strength-can be used for load bearing walls.
6. Eco friendly using Fly Ash.

Fly Ash bricks Disadvantage:
1. Bonding is lower due to smooth finish, this can be easily
corrected by using a cement:sand mortar of 1:4 and proper
curing. Also the quality of sand needs to be checked.

Clay Bricks Disadvantage:
1. Uneven shape
2. Labour Intensive.
3. Inefficient Kilns Coal Fired -Pollution
4. Cutting of agricultural land and hills -Pollution and
against world food security.

Cost waise Fly ash bricks is not that costly due to
machines produce the bricks. labor requierment is less and
stregnth is more by adding plaster of paris and cement.

Clay bricks now days not not that strong becuse of clay
quulity and less skill laboer produce such bricks.

clay bricks color is beauliful becuse it is natural but
ultimaly we have to cover with more plaster. so no point
of color of bricks.

Clay bricks is heavy so deal load on buiding is more;
many points.
