It was observed that with use of crusher dust at all replacement levels, the workability of concrete was reduced from 1-6%. From the test results, it was observed that the replacement of natural sand by crusher dust increased the compressive strength of concrete by 5-22%.
Answer (1 of 2): It is good to be creative and to think outside the square. However there are sometimes that things have been done a certain way for a long time for a good reason.
Stone dust is a waste material obtained from crusher plants. It has potential to be used as partial replacement of natural river sand in concrete.
It was observed that with use of crusher dust at all replacement levels, the workability of concrete was reduced from 1-6%. From the test results, it was observed that the replacement of natural sand by crusher dust increased the compressive strength of concrete by 5-22%.
The mix design is targeted for M30 grade concrete with w/b ratio 0.43. The investigation comprises of 12 numbers of concrete mixes. First two mixes were made by replacing 0 and 50% of natural fine aggregate (NFA) with crusher dust (CD). Then at each replacement level of NFA, cement is replaced partially with both fly ash (FA) and silpozz.
Many studies have examined the influence of the partial replacement of fine aggregate in concrete using crusher dusts or small crushed sand samples on concrete properties [8,12,13]. However, little work has been performed on the complete replacement of natural fine aggregate in concrete with crusher dusts.
An attempt has been made through this study to find out a suitable mix proportion of desired strength by replacing sand with crusher dust in cement concrete, at the same time retaining its quality.

It was observed that the replacement of natural sand by crusher dust increased the compressive strength of concrete by 5-22% and it was also found that amongst all the mixes, the highest compressive strength was obtained for 40% replacement of sand by crusher dust (Quadri et al., 2013). The required slump could not be achieved by

Two grades of concrete M20 and M25 having nominal mix proportion of 1:1.5:3 and 1:1:2 respectively were used by weight and w/c ratio was fixed according to the slump requirement of 60mm. For this concrete mix, quarry dust was added for replacement of sand from 0% to 100% in step of 10%.

replacement of natural sand. It was observed that with use of crusher dust at all replacement levels, the workability of concrete was reduced from 1-6%. From the test results, it was observed that the replacement of natural sand by crusher dust increased the compressive strength of concrete by 5-22%.
The suitability of quarry dust as alternative material for the river sand in concrete manufacturing is studied. M25 grade concrete was prepared with 0%, 20%, 40%, 60%, 80% partial replacement of

sand replacement by quarry dust major project – Grinding Mill …. replacement of natural sand by quary dust. sir i like to replace the natural sand with available quary dust in my projects is there any papers which suggest …
Two grades of concrete M20 and M25 having nominal mix proportion of 1:1.5:3 and 1:1:2 respectively were used by weight and w/c ratio was fixed according to the slump requirement of 60mm. For this concrete mix, quarry dust was added for replacement of sand from 0% to 100% in step of 10%.
Replacement of sand by quarry dust in concrete Products. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, Replacement of sand by quarry dust in concrete, quarry, aggregate, and different kinds of minerals.
Can I use crusher dust instead of sand in concrete? From the experimental study, it is concluded that the quarry dust can be used as a replacement for fine aggregate. It is found that 40% replacement of sand by quarry dust gives maximum result in strength compared to normal concrete and then decreases from 50%.
EXPERIMENTAL STUDY ON COIR BLENDED CONCRETE … powder as replacement of sand and partial replacement of cement with fly ash in concrete. The percentage of granite powder added was 0%, 25%, 50%, and 75% by weight as a replacement of sand used in concrete and cement was replaced with 10% fly ash.
It was observed that with use of crusher dust at all replacement levels, the workability of concrete was reduced from 1-6%. From the test results, it was observed that the replacement of natural sand by crusher dust increased the compressive strength of concrete by 5-22%.

to study the effect of partial replacement of fine aggregates by quarry dust and cement by fly ash on cement concrete. 1.2 NEED FOR INVESTIGATION Quarry Dust These residues are generally less than 1% aggregate production in the normal concrete. The introduction of quarry dust for mixing is limited due to its high fineness.

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%.
