Fresh density was increased with the increase of quarry dust and billet scale (QD+BS) as shown in Fig. 2. As far as the weight is concerned, billet scale is a heavy weight material as it is shown above and quarry dust is also a heavy weight material since its specific gravity is 2.97. Therefore, the fresh density was directly proportional to QD+BS.
Quarry Dust. Quarry dust is a byproduct of the crushing process which is a concentrated material to use as aggregates for concreting purposes, 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. Enquiry on ...
