RESULTS AND DISCUSSION A.Workability of Sustainable development: Using stone dust to replace a ,Many researchers have done researches to find out the effect of stone dust to replace part of sand in concrete mixture [915]. Sankh at all [15] found that many alternative materials such as copper slag, ground granulated blast furnage slag (ggbs), washed bottom ash, quarry dust foundry sand, etc., which could replace natural sand in concrete
replaced with stone dust (Franklin et al 2014). The compressive strength of concrete mix had increased by 22% with the use of crusher dust at 40% replacement of natural sand (Pofale et al 2013).The present study aimed to utilizing stone dust as fine aggregate in concrete in place of natural fine aggregate.Effects of crushed stone dust on some properties of concrete,Abstract. 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.

properties of concrete when the Natural sand is partially replaced with stone dust. Keywords: Concrete, sand, Quarry dust, compressive strength, Natural sand I INTRODUCTION GENERAL For the development of any structure, Concrete is the main material. The principle fixing to produce concrete is Portland cement.Study of Mechanical Properties of Concrete Incorporated ,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. Influence of stone dust as fine aggregate replacement ,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 100% 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
B. Cement is replaced by glass powder at constant 12 % and natural sand are replace by stone dust in different percentages like 0%, 10%, 20%, 30% ,40% and 50 % to study the effect of Glass Powder and Stone Dust on hardened properties of concrete such as compressive, Split tensile and Flexural strength of concrete at 7, 14 and 28 days. C.Natural Sand Or Stone Dust In Concrete Pavementphp ,Without waterproof knee pads kneeling on wet concrete can irritate or burn the skin. Cement dust released during bag dumping or concrete cutting can also irritate the skin. Moisture from sweat or wet clothing reacts with the cement dust to form a caustic solution. Allergic skin reaction. Some workers become allergic to the hexavalent chromium .Effect of stone dust on strength of concrete: A Review,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. Studies shows that stone dust can be used as an alternate material for natural sand to some extend for the preparation of concrete.
Concrete plays a major role in the construction industry. Natural sand is a prime material used for the preparation of concrete and also plays an important role in Mix Design. Now a day's river erosion and other environmental issues have led to the scarcity of river sand. The reduction in the sources of natural sand and the requirement for reduction in the cost of IOP Conference Series: Materials Science and ,It is clearly observed that there is reliable increase in the strength of plain concrete when natural sand is fully replaced by quarry dust, Mahendra R. et al. [9]. R. IIangovana [12], the study gives attention towards physical and chemical properties of quarry dust are satisfied in respect of requirements of codal provision.Crushed stone dust as a replacement for river sand in self ,A 53grade Ordinary Portland cement, of specific gravity 3.15, confirming to IS: 1489(part1)1991 [19], has been used.Locally available river sand, crushed stone dust and foundry sand conforming to Zone2 as per IS: 3831970 [20] are used as fine aggregate.

Abstract. 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 Evaluation of Crusherdust as Replacement of Filler in ,To investigate the possibility of using crushed stone dust as fine aggregate partially with different grades of concrete composites. The suitability of crushed dust as fine aggregate for concrete has been assessed by comparing its basic properties with that of controlled concrete. One mix was selected for natural sand to achieve M30 grade concrete.“REPLACEMENT ON NATURAL SAND BY STONE DUST”,The stone dust is not only the alternate but is superior in different ways. Literature Review: 1. Stone Dust in Concrete: Effect on Compressive Strength: 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
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 100% by weight.

If 50% replacement of sand 450 kg per meter cube cement needed to achieve the target means strength for M25 grade. Also, the increase in watercement ratio didn’t yield a positive result.
