Effects of crushed stone dust on some properties

01-07-1996  Crusher dust is a fine material formed during the process of comminution of rock into crushed stone or crushed sand. This dust is composed by particles which pass 75 μm BS sieve. Effects of dust content in aggregate on properties of fresh and hardened concrete are not known very well. An experimental study was undertaken to find out the effects of various proportions of dust content on properties

Stone Dust. Stone dust, also known as stone screenings, is the finest of the types of crushed stone. Although it is made from the same type of stone as the other two types, it is crushed into a powder. When used by itself stone dust forms a hard surface that is water resistant. When used with a larger stone it acts as a binding agent.
