Stone dust can substitute river sand as fine aggregate in concrete. Ceramic waste can replace 10–20% of coarse aggregates without impacting material structure. Ceramic waste can replace coarse aggregates [17]. The mechanical characteristics of normal concrete with quarry dust (2011). In the experiment, quarry dust replaced sand …

This paper deals with the use of CRD as filler material in producing concrete. Cement is replaced with five percentages (C30-0%, C31-10%, C32-20%, C33-30% and C34-40%) of CRD by weight. Dynamic elastic modulus (Ed) Workability, density, flexural strength, compressive strength and ultrasonic pulse velocity (UPV) are experimentally …

A complete replacement of quarry dust to river sand as fine aggregate in concrete is possible with proper treatment of quarry dust before utilization (Illangovan et al 2008).The utilization of ...

Crusher dust is one of the alternatives for sand especially when some states have already banned the use of river sand for construction. "Crusher dust is a common by-product of …

Many studies show that this replacement can improve the strength of conventional concrete, high-performance concrete, and mortar, due to the higher bond between the rough angular crushed sand particles on one hand, and the higher interlocking between the sharp-edged crushed sand and the cement paste on the other hand (Donza et al. 2002 ...

Fine and Coarse aggregate are basic need of construction industry and can be replaced by quarry dust which is a byproduct of rubble crusher units. It contains some Geotechnical and mineralogical characterization which can easily interact with soil. ... Effect of quarry dust as partial replacement of sand in concrete Indian streams research ...

Instead of disposing them in landfills, it can be best utilized as partial replacement to sand. 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 replaced to the amount 25%. Its Availability is not a concern.
