Impacts of Using Crushed Rocks in Concrete (Civil Project ...

Concrete in Sweden has traditionally been manufactured with natural aggregate from glaciofluvial eskers. There is a need to preserve the remaining eskers because of their cultural value and importance for water filtration, thus natural aggregate has to be replaced. The most realistic alternative is to use crushed rocks.

Effects of crushed stone dust on some properties of concrete

Abstract. 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 ...

Feb 03, 2012  Crushed vs Round aggregate in concrete. ACI 318-05 and -08 does not appear to reward the designer for specifying crushed aggregate over rounded (usually "river rock") in structural concrete. Chapter 4 refers to ASTM C33, and leaves it at that. Certainly crushed rock has better interlock, and must have better shear friction for roughened surfaces.
