We are investigating the potential of using quarry waste and its effect on the strength and workability of concrete. This paper reports the experimental study which investigated the partial replacement of sand with quarry dust. Initially cement concrete cube was studied with various proportions of cement concrete + quarry dust (M 20, AND M25).
Quarry dust a byproduct of stone crushing has been proposed as an alternative to sand that gives additional benefit to concrete. Quarry dust is used to increase the strength of concrete over concrete made with equal quantities of sand. Quarry dust has been used for different activities in the construction industry such as in road
replace cement. Stone dust was used in place of cement in amounts of 3, 5, and 7%. Similar to this, stone dust was used in place of sand at a ratio of 15 to 50 with a 5 percent increase. According to test results, the compressive strength of the mould grows to 21.33% and 22.76% in that order when compared to the
Quarry rock dust (QRD), a waste obtained during the quarrying process is a significant source of air pollution yet has the potential of becoming a sustainable and economical alternative to sand in concrete. Studies confirmed that replacing sand in conventional concrete with QRD increases its durability and robustness by ten percent.
shows that the sand has 1% gravel along with 15.4% coarse sand, 27.4% medium sand and 53.2% fine sand. The sand also has a small percentage of silt clay, about 3%. Sand has ... It is observed from experiment 5 using Fly ash, stone dust, and cement in the proportion of 47.2:42.5:10, a mean strength of 8.89 MPa is obtained. By increasing a …
— This paper presents the experimental investigation of mechanical properties of brick masonry using stone dust as partially replacement with sand in masonry mortar. ... throughout the work and two different …
Sand is ultimately a much safer option than stone dust for paving projects. However, this is not a black-or-white issue. You may choose to use stone dust if you have a large supply of it, or prefer the texture and appearance of it. Before settling on stone dust, just be aware that you may face shifting or other issues caused by the material's ...
reducing the percentage of sand/stone dust to 20 % and a small percentage of cement is reduced, the stres s carrying capacity of the brick is increased to 11.04 Mpa.
Highlights. •. Sawdust ash (SDBA) addition slightly improved interlocking blocks' strength properties. •. 20% SDBA can optimally replace cement to achieve …
obtained at lower cost. One such material is Quarry stone dust: a by-product obtained during quarrying process. Attempts have been made to study the suitability of Quarry dust as sand replacing material and it has been found that Quarry dust improves the mechanical properties of concrete as well as elastic modulus. The optimum
Concrete using lateritic sand and quarry dust as fine aggregates exhibit three basic forms of slump depending on the water/cement ratio just like normal concrete (i.e., True, Shear and Collapse). This can be seen in the slump results shown in Figure-3 (a to c). The slump is between 0 and 175mm. Figure-3.
The fine aggregate used in mixtures are natural sand and stone dust. Locally available river sand which is the natural sand and stone dust from the quarry passing through 4.75 mm sieve and retained on 75 micron sieve is used. Quarry rock dust crushed sand less than 4.75 mm is produced from hard granite rock using state of crushing plants.
