Oct 06, 2020· The fine aggregate is natural sand that has been washed and sieved to remove particles larger than 5 mm, and the coarse aggregate is a gravel that has been crushed, washed and sieved so that the particles vary from 5 to 50 mm in size.The fine and coarse aggregate is delivered separately. As they need to be sieved, a prepared mixture of fine and coarse aggregate is more expensive than the
On the other hand, studies conducted by (Opara et al. 2018) have also shown that river sand concrete has a higher density and compressive strength than quarry dust concrete for all curing ages
Concrete, Gravel: 150 lb/ft 3: 2,400 kg/m 3: Crushed Stone: 100 lb/ft 3: 1,600 kg/m 3: Earth, loam dry excavated: 90 lb/ft 3: 1,440 kg/m 3: Earth, packed: 95 lb/ft 3: 1,520 kg/m 3: Glass, window: 161 lb/ft 3: 2580 kg/m 3: Gravel, loose, dry: 95 lb/ft 3: 1,520 kg/m 3: Gravel, with sand: 120 lb/ft 3: 1,920 kg/m 3: 3/8 inch Gypsum or Plaster Board

The results showed that river sand concrete had greater density and compressive strength than quarry dust concrete for all curing ages. At 28 days of curing, river sand concrete exceeded the target compressive strength by 36%, whereas quarry dust concrete was less than the target compressive strength by 12%.

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.
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. 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
In the light of these known hazards from gravel dust it is essential that evidence is available (perhaps from existing gravel quarries) of the extent to which PM 10 and PM 2.5 particles of crystalline silica dust can be expected to be found (say over the course of a year) at distances of say one, two and four kilometres from quarry workings
Jan 01, 2020· 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. The grading curve river sand vs Quarry and standard curve as shown in the Fig. 1 .
Sand with Gravel, dry weighs 1.65 gram per cubic centimeter or 1 650 kilogram per cubic meter, i.e. density of sand with Gravel, dry is equal to 1 650 kg/m³. In Imperial or US customary measurement system, the density is equal to 103.006 pound per cubic foot [lb/ft³], or
Jun 06, 2016· 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 study compared the physical and mechanical properties of river sand concrete with quarry dust concrete. The constituent materials were batched by weight. The water-cement ratio and mix ratio selected for the experimental investigation were 0.55 and 1:2:4, respectively. The specimens were cured for 7, 14, 21 and 28 days. Slump, density and compressive strength tests were carried out.
