Study on Compressive Strength of Quarry Dust as Fine . The particle size distribution for quarry dust was The cubes were casted using standard cubes of 150 mm × 150 mm × 150 mm. The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. Quarry Dust 1. Mix Design Mix design was carried out using IS:10262-(2009). The quarry dust was collected from the dumps of quarry near chickballapur, Karnataka. IV. 634 2.755 2. Specific gravity of quarry rock dust : 2.68 Specific gravity of coarse aggregate : 2.83 Table 2.7 Determination of specific gravity 2.10 BULK DENSITY The mass of the material in a given volume and it is expressed in kg/m3. Wet sieving of quarry dust through a 90 micron sieve was found to be 78 and the corresponding bulking value of quarry dust was 34.13 . Quarry dust The basic tests on quarry dust were conducted as per IS-383-1987 and its specific gravity was around 1.95. 2: Specific gravity for 40 quarry dust crusher samples It was observed that all the samples of quarry dust are in the range of sand, indicating that soil with high silt content replaced by the quarry dust will reduce the swelling and shrinking of the soil. 1. MATERIAL PROPERTIES 4.1 Quarry dust The suitability of the material was determined by analyzing particle size distribution, specific gravity and chemical composition. As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft. SPECIFIC GRAVITY: The specific gravity of an aggregate is considered to be a measure of strength or quality of the material. Specific gravity of sand= 2.56 Specific gravity of quarry dust= 2.57. The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. … The tests will be carried out on both the natural sample and the improved sample and will include: moisture content, specific gravity, grain size distribution, Atterberg’s limits, compaction and California Bearing Ration (CBR) tests both before adding quarry dust and after adding a varying percentage and proportion of quarrying dust. The physical properties obtained from the tests performed on the quarry dust and sand were incorporated in the mix design for 72 3.59 Figure 1 Particle Size Distribution B. Coarse aggregate replacement of sand with quarry dust of mortar cube (C. Cited by 11 Get Price Quarry stone dust was replaced in river sand from 0 to 50% for various mixes and having a specific gravity of 2.42, fineness modulus of 3.12 and confirming the Zone II as prescribed in IS 383-1987. Download : Download high-res image (325KB) specific gravity of quarry dust of crusher samples as shown in Figure no. Specific gravity: 2.53 Fineness modulus: 3.08 Density: 1.63gm/cc Void ratio: 0.55 2.3 Quarry Dust: - Quarry dust is a byproduct of the crushing process which contains particle size from 0.75 to 5 mm. 2 Figure No. Water Absorption 0. Because Quartz Sand is nonporous - and because it is an extremely adamant mineral - Quartz will not decay into dust or dissolve and wash away: as will all other typical minerals or sands. Stones having low specific gravity are generally weaker than those with higher specific gravity values. Specific gravity of sand and quarry dust of 2.62 and 2.70 for Zone II classified type is obtained. Specific Gravity 2. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic meter). 53 grade cement is used for the mix. These stone dust are not usable and dumped for land filling. The grading curve river sand vs Quarry and standard curve as shown in the Fig. Specific gravity of marble powder=2.58.
