2.3. Coarse Aggregate. Locally available crushed igneous rocks from Pakur with 16 mm graded size have been used as coarse aggregate. The physical properties for the coarse aggregate as found through laboratory test are as follows: Aggregate crushing value = 24%. Aggregate impact value = 29%. Specific gravity = 2.713. Water absorption = 0.755.

Then crushed aggregates are then sieved through 2.36 mm sieve and weight of passing material is expressed as percentage of the weight of the total sample which is the aggregate crushing value. A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates.

Quarry dust is a waste from the crushing unit which accounts 25%-30% of the final product from stone crushing unit and a reason to cause environmental pollution. Quarry dust can be used as an admixture in concrete efficiently to lessen its impact on environment and human. It can also be used as partial replacement of cement in concrete. Cement can be replaced partially by quarry dust in

Indian Standard specifications. Coarse Aggregate:- Aggregate of 26.5 mm is used as coarse aggregate in this experimental program. Coarse aggregate was locally procured. The aggregate should be free from dust (such that properly washed and dried for at least 72 hours before batching) and must not be alkali reactive.

Quarry dust is a byproduct of the crushing process which is a concentrated material to use as aggregates for concreting purpose, especially as fine aggregates. In quarrying activities, the rock has been crushed into various sizes; during the process the dust generated is called quarry dust and it is formed as waste. So it becomes as a useless material and also results in air pollution
