ADVANTAGES :-
1. Due to high strength, practically no breakage during transport & use.
2. Due to uniform size of bricks mortar required for joints & plaster
reduces almost by 50%.
3. Due to lower water penetration seepage of water through bricks is
considerably reduced.
4. Plaster of Paris / Gypsum Plaster can be directly applied on these
bricks without a backing coat of plaster
5. These bricks do not require soaking in water for 24 hours. Only
sprinkling of water before use is enough.
