Concrete is very variable material, having a wide range of strengths and stress-strain curve. Concrete composite material whose basic properties are related to the characteristic of constituent element, especially the aggregate. This research aimed to investigate the effect of replacing sharp sand with stone dust as an alternative to only river sand.
Can you use any stones for concrete? Aggregates in any particular mix of concrete are selected for their durability, strength, workability and ability to receive finishes. – Fine aggregates are usually sand or crushed stone that are less than 9.55mm in diameter. • Typically the most common size of aggregate used in construction is 20mm.
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).
1. For the designed mix proportions of M25 and M40 grades of concrete the desired characteristic strengths for cubes are achieved in both conventional concrete and Quarry Stone dust concrete. 2. The strength achieved in concrete made with sand as fine aggregate achieved high strengths when compared with Quarry stone dust concrete.
Experimental programme was conducted using 30%, 40%, 50%, 60% and 70% partial replacement of fine aggregate with stone dust has been taken for concrete …
Experimental programme was conducted using 30%, 40%, 50%, 60% and 70% partial replacement of fine aggregate with stone dust has been taken for concrete of M25 grade with 0.46 water cement ratio ...
Concrete of M25 grade was designed for a w/c ratio of 0.48 for the replacement of 10% coarse aggregate with recycled coarse aggregate and replacement of 50, 60 and 70% of fine aggregate (sand ...
The test result indicates that crushed stone dust waste can be used effectively used to replace natural sand in concrete. In the experimental study of strength characteristics of concrete using crushed stone dust as fine aggregate it is found that there is increase in compressive strength, flexural strength and tensile strength of concrete.
of fine aggregate with stone dust. The results shows strength of concrete increases within 5-12 percent up to 50 percent replacement of fine aggregate. And at 60 percent stone dust in concrete the maximum value of compressive strength is obtained which is 17 percent more than referral concrete (concrete with zero percent stone dust).
Lakhan Nagpal, Arvind Dewangan (2013), Evaluation of Strength Characteristics of Concrete Using Crushed Stone Dust as Fine Aggregate presented in his research Mixture of stone sand and natural sand can be used for medium grade concrete. If better quality of stone sand can be used, it may give better result in terms of strength.
Abstract: River sand is most commonly used fine aggregate in the production of concrete Quarry stone dust has many of the useful properties of the stone that it comes from. It is very heat resistant and poses the problem of acute shortage in many areas. Quarry rock dust can be an economic alternative to the river sand.
of crushed stone dust waste as fine aggregate for concrete has been assessed by comparing its basic properties with that of conventional concrete. Two basic mixes were selected for natural sand to achieve M25 an M30 grade concrete. The equivalent mixes were obtained by replacing natural sand by stone dust partially and fully.
this case the stone dust was added to concrete without any processing or adjustment. So, concrete samples were made by replacing varying percentages of natural sand by stone dust in 30% and by weight. All the concrete mixtures were performed using IPT/EPUSP's method.13 The workability was fixed at 80±10 mm based in the slump

Quarry dust can be utilized in concrete mixtures as a good substitute for natural river sand giving higher strength at 50% replacement (Balamurgan et al., 2013). While using crushed stone dust as fine aggregate in concrete it is found that there is increase in compressive, flexural and tensile strength of concrete (Nagpal et al., 2013). It has ...
The test result showed that concrete with sharp sand as fine aggregate develop a strength of 28mpa on the 28th day while quarry concrete at the same age developed a strength of 32.8mpa indicating a 17% more compressive strength of the stone dust over the sharp and concrete (Prakash and Kumar 2004).
