Nanda et al. (2010) have conducted test on stone crusher dust as fine aggregates in concrete for making paving blocks. They found that replacement of fine aggregates by crusher dust up to 50% by weight has a negligible effect on the reduction of compressive, flexural and split tensile strength.
In the crusher machine after crushing of stone the product retained known as Compatibility of Superplasticizers and Cement: crushed stone dust. If can be used as a fine - aggregate in cement concrete as a replacement of It has been noticed that all sand it may be replace fully or partially as a superplasticizers are not showing the same extent ...
The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity. The availability of sand at low cost as a fine aggregate in concrete is not suitable and ...
Answer (1 of 7): Of course. Quite a standard procedure. We call it crusher dust, or manufactured sand. Dependent on the source rock and type of crusher, the particle shape is unlikely to be nice round grains, which makes for concrete that is not quite as nice to play with, but it is still far fr...
The Narmada River sand is used as NS. (ii) Crushed Stone dust is a fine material formed during the process of conversion of rock into aggregate and has particle size ranging from 4 mm to dust size (> 0.075mm). It was procured from stone crusher plant producing 20 mm downgraded aggregate, M/s Maa Pitambara Stone situated at Neelbad, Bhopal (India).

Compressive strength of concrete made using 05 % ceramic waste aggregate and 05 % stone dust as replacement of coarse aggregate and fine aggregate respectively, is about 20% more than that of referral concrete at 28 days. However, compressive strength at 05% recycled aggregate and 05% stone dust is marginally than that of conventional concrete.
Sahu et al investigated the use of crusher dust only as a partial replacement of fine aggregates, and not as complete replacement, while Jaffar et al investigated the performance of high strength concrete with silica stone dust was a partial replacement of cement. Further, comprehensive tests on beam models are not reported so far.
