The use of quarry dust for SCC appliions

The use of quarry dust for SCC appliions

 · Granite fines are often referred to as quarry dust, a byproduct in the production of concrete aggregates during the crushing process of rocks. For the materials supplied, the granite particles were finer than the limestone powder. The shape of the granite fines tends to be flakier and more elongated than the limestone particles.
