Study on Replacement of Sand in Concrete with Crushed Stone Dust. Authors: Naresh Kalaskar. Osmania University. Abstract. The purpose of this study was …
Quarry dust can be partially used as an alternative to river sand, as fine aggregate in concrete production. It is basically a by-product of stone crushers produced during the …
The optimum river sand replacement level using quarry dust ranges between 25% to 70%. Besides, the inclusion of QD as NRS replacement material tends to reduce the magnitude of length change due to drying shrinkage.
In crusher dust, the particles (% finer than 150 microns) are generally high, a major concern limiting its percentage replacement to minimum with sand in a concrete mix. It can be …
The ideal percentage of the replacement of sand with the quarry dust is 55% to 75% in case of compressive strength. The further increasing the percentage of replacement can …
