Substitutes or Alternatives of Bricks used for Construction in India
Article shared by : 
Substitutes or Alternatives of Bricks used for Construction in India! According to one study, our country needs about 60 billion bricks every year and if no suitable substitute is found out, this would exhaust about 1600 x 106 kN of clay fields or other agricultural land annually. It will thus make barren about 3000 hectares […]
Comparison: Clamp-Burning and Kiln-Burning of Bricks | Engineering Material
Article shared by :
Learn about the comparison or differences between clamp-burning and kiln burning of bricks. Comparison # Clamp-Burning: 1. Capacity: About 20000 to 100000 bricks can be prepared at a time. 2. Cost of Fuel: Low as grass, cow dung, litter, etc. may be used. 3. Initial Cost: Very low as no structures are to be built. […]
