ash (major ingredients) generated at Barapukuria Thermal Power Plant, sand, hydrated lime and gypsum and also optimized the brick forming pressure. Fly ash- 55%, sand- 30% and hydrated lime – 15% with gypsum-14% was found to be the optimum mix. For the optimum mix studied the compressive strength, microstructure,

Sand is typically extracted from natural sources through different methods, depending on the location and type of deposit. River sand is naturally occurring sand found in riverbeds or banks. One of the most widely used construction materials, concrete is a mixture of cement, aggregates (such as sand and gravel), water, and additives.

Coal fly ash, a burnt residue of pulverized coal, is hazardous and its disposal is a problem. In Bangladesh, the annual generation of this waste is approximately 0.6 million tons. On a global basis, less than 20 percent of coal fly ash (CFA) is used in the concrete related applications while the remainder is disposed of in landfills leading to various …

Fly Ash/Sand : Lime : Cement : Gypsum = 69 : 20 : 8 : 3. Aluminum is about 0.08% of total dry materials in the mix and the water ratio is 0.6 - 0.65. Fly ash is pumped into a container. Once the desired weight is poured in, pumping is stopped. Similarly, lime powder, cement, and gypsum are poured into individual containers using conveyors.

The rise and fall of the sea level millions of years ago started the process of making the gypsum sand that covers the monument today.
