Various physical properties of the concrete materials are tabulated in Table 1. Table 1: Properties of the materials Material Properties
Quarry dust a by- product from crushing process during quarrying activities is good alternative during construction projects. It is used as substitute to sand to make quarry dust concrete which is believed to be stronger and more durable than the regular concrete materials. Uses of Quarry Dust. It can be used as substitute to sand wholly or partly.
This paper present a report on the possibility of developing high performance concrete (HPC) using quarry dust as part of fine aggregates. Quarry dust was used to replace 20% of sand in silica fume-quarry dust (SFQD) and silica fume (SF) concretes. Besides, silica fume was used as 10% replacement of cement in both SF and SFQD concretes.
From the results of experimental investigations conducted, it is concluded that the quarry dust can be used as a replacement for fine aggregate. It is found that 40% replacement of fine aggregate by quarry dust gives maximum result in strength than normal concrete and then decreases from 50%.
Previous studies have shown that replacing sand with quarry rock dust produces concrete with about 8–20% increases in strength. The use of quarry dust as replacement for sand in concrete has been extensively researched in recent years.
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. The problem is that using what I would call "crusher dust" …

To overcome this problem, present study is focused on the suitability to utilize the quarry dust in Self Compacting Concrete (SCC) partially as fine aggregate with the natural fine aggregates. In this work, quarry dust is used as replacement of sand in a different level (0%, 15%, 30%, 45% and 60%) for producing the SCC.
Keywords: crushed limestone dust, sand, SCM, rheology, strength. Date: 9/14/2012. Abstract: Limestone quarry dusts are fine materials obtained during the process of crushing rock to produce gravel. The effects of dust content in crushed limestone sand on the properties of fresh and hardened self-compacting mortar are not well known.
found that the compressive and flexural strength of concrete made of Quarry Rock Dust are nearly 10% more than the conventional concrete (Suribabu et al., 2015). In the present study it is proposed to investigate the optimum replacement of river sand with stone dust for concrete in term of compressive strength performance at 7 days and 28 days. II.

Quarry dust is a waste obtained during quarrying process. It has very recently gained good attention to be used as an effective filler material instead of fine aggregate. Also, the use of quarry dust as the fine aggregate decreases the cost of concrete production in terms of the partial replacement for natural river sand.
mix quarry dust in sand then only 65% to 75% of sand replaced by quarry dust because strength of concrete is affected by this process. In other process if we mix quarry dust and fly ash are added together in concrete mix then we replace complete sand by quarry dust and fly ash. The use fly ash in concrete is desirable because of benefits such as useful
The replacement of natural fine aggregate by using quarry dust leads to consumption of generated quarry dust, the requirement of land fill area can be reduced and solves the natural sand scarcity problem. The sand availability as a fine aggregate at low cost which needs the reason to search as a alternative material.
cement industries use fly ash to improve the volume. quarry dust also contains a similar property of river sand. quarry dust is used in concrete to minimize the demand of river sand. maximum exploitation of sand is to be minimized to protect the river beds, shore structures from erosion.
