A loss in chlorophyll-a and chlorophyll-b content in leaves of plants treated with stone dust supported the argument that the chloroplast is the primary site of attack by stone crushing dust pollutants. The present results clearly indicate that the stone crushing dust adversely affect the growth and yield status of

Crusher dust is a fine material formed during the process of comminution of rock into crushed stone or crushed sand. This dust is composed by particles which pass 75 μm BS sieve. Effects of dust content in aggregate on properties of fresh and hardened concrete are not known very well. An experimental study was undertaken to find out the effects of various proportions of dust content on properties of fresh

2017-8-24 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. In the present investigation, an experimental program was carried out to study the workability and compressive strength of concrete made using stone dust as partial replacement of fine aggregate in the range of 10% - 100%. M25 grade of concrete was designed using Portland pozzolana cement (PPC) for referral concrete. Workability and Compressive strength were determined at different replacement level of fine aggregate viz a viz referral concrete and optimum replacement level was determined based on compressive strength. Results showed that by replacing 60% of fine aggregate with stone dust concrete

Concrete paving blocks are ideal materials on the footpaths for easy laying, better look and finish. In this paper, a parametric experimental study for producing paving blocks using crusher dust is presented. Some of the physical and mechanical properties of paving blocks with fine aggregate (sand) replaced by various percentages of crusher dust are investigated.

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 ...

2013-12-24 The suitability of the stone for quarrying depends on its quality, the possibility of cheap and ready conveyance to a large market; and its inclina-tion and depth below the surface. The two principal branches of the industry are the di-mension stone and crushed-stone quarrying. In the for-mer, blocks or sheets of stone, such as marble, are ex-
