INTRODUCTION Concrete is a mixture of water, cement or binder and aggregates (fine and coarse aggregate) and is a commonly used material for construction (Barritt, 1984).
concrete strength by 34% over the strength produced by concrete with sand and gravel of 28mm maximum size. Also, as coarse aggregates' size increases, normal concrete strength decreases. The rate of fall in strength is highest with the concrete containing quarry dust as a fine aggregate. However, the case of laterized concrete was not studied.

compressive strength than normal concrete and 50% crusher dust concrete. It can also be observed that replacement of crusher dust has shown more compressive strength than normal concrete and 50% crusher dust concrete as well as it is gradually increasing form initial day of curing to final day of curing i.e., up to 28 days of curing.
Mix Design The design mix proportion of 1:1.65:3 at W/C ratio of 0.50 were used for M25 grade of concrete and the cement content was 380 kg/m3, satisfying the requirements of IS-10262-2009. RESULTS AND DISCUSSION 1. The compressive strength of concrete made using stone dust at different proportion is shown in table 6. 2.
Compressive Strength of Concrete Made with Quarry Rock Dust and Washed 10mm Washed Gravel as Aggregates. American Journal of Engineering, Technology and Society. Vol. 2, No. 2, 2015, pp. 26-34. Abstract This work is related to study the compressive strength of concrete using quarry dust as fine aggregate instead of sand and
Stone Dust in Concrete: Effect on Compressive Strength. Abstract- 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. Use of stone dust in concrete not only improve the quality of concrete but also conserve the natural river sand for future generations.

This paper aims to focus permeability study of self-compacting concrete (SCC) made with industrial wastes, i.e., marble sludge powder (MSP) from marble processing and crusher rock dust (CRD) from stone crushing industries. MSP can be used as filler and it helps to reduce the total voids content in concrete.

For C55 strength grade concrete, the impact of the two production processes of machine-made sand on the compressive strength of concrete is more obvious. The compressive strength of concrete prepared with dry-process machine-made sand (3d, 7d, 28d and 56d) is higher than that of ordinary process manufactured sand: 5.5 %, 9.6%, 10.1% and 5.8%.
concrete is a concrete having compressive strength greater than 40MPa, made of hydraulic cements and containing fine and coarse aggregates; and discontinuous, unconnected, randomly distributed steel fibers. The present study aims at, developing concrete mixtures incorporating marble dust as partial replacement of cement as well as steel fibers.
