Conventional concrete aggregate consists of sand (fine aggregate) and various sizes and shapes of gravel or stones (coarse aggregate). However, there is a growing interest in substituting alternative aggregate materials, largely as a potential use for recycled materials. While there is significant research on many different materials for aggregate substitutes such as granulated coal ash, blast ...

5. Manpower and Skilled Labour. There's nothing much skillful in manufacturing bricks. The only thing necessary is to look for mortar and clay quality, ratio of clay-water, cement-sand-water and the time and temperature necessary for baking the bricks. These things aren't very hard to grasp for anyone.
