Quarry dust according to the global research can effectively replace 50-60% of sand in conventional concrete. Thus the entire purpose of the study was to experimentally determine the feasibility of use of quarry dust in replacement of sand in …
In most cases, the Quikrete concrete mixture is made of sand, gravel, and Portland cement. If you are looking for something less strong but more flexible, Quikrete also offers mortar mixtures, which are softer than concrete. Their concrete mixtures have a wide variety of set time, which can go from as short as 30 minutes to as long as 24 hours.
The performance of concrete using stone dust as a replacement to sand. Sand was replaced by quarry dust from 0 to at an increment of 25%. Compressive strength and tensile strength tests were conducted using 43 grade OPC in M20 concrete. Compressive strength was computed at the age of 7 days, 28 days, and 60 days.
Utilization of quarry dust in concrete is recommended particularly in regions where sand is not easily available (Dehwah [ 5 ]). Muhit et al. [ 6] determined that passing from 200 mm sieve is used as …
It is conventional that sand is being used as fine aggregate in concrete. The river deposits are the most common source of fine aggregate. Now-a-days the natural …

Two grades of concrete M20 and M25 having nominal mix proportion of 1:1.5:3 and 1:1:2 respectively were used by weight and w/c ratio was fixed according to the slump requirement of 60mm. For this concrete mix, quarry dust was added for replacement of sand from 0% to in step of 10%.
Therefore, this study investigates ternary and quaternary blended cement comprising laterite, calcined clay and calcite as partial cement replacement in sandcrete hollow blocks. In addition, quarry dust was utilized as replacement of river sand.
It has potential to be used as partial replacement of natural river sand in concrete. Use of stone dust in concrete not only improve …
Ebrahim ( 2018) studied the mechanical behavior of C25 and C30 grade of concrete by partially replacing cement with quarry dust by 5%, 10% 15% and 20% (PPC and OPC). The optimum replacement of cement by quarry dust recorded from the findings was 5% and 10% for PPC and OPC, respectively.
The study has conducted to determine the workability and compressive strength of the self –compacting concrete. The sand has replaced with quarry dust with the proportion of 10, 20, 30 and 40% and super plasticizer was added 0.9%. The experiments were carried out at the Infrastructure University Kuala Lumpur (IUKL) concrete laboratory.
Concrete used was prepared by replacing 25% and of sand by weight with quarry dust. Also, conventional sand concrete was prepared as reference concrete for comparison. 100 mm cube and 100 × ...
One of the main disadvantage of concrete is the large usage of river sand as a filler material, which leads to eco-friendly concrete. An experimental investigation has been done to effect of fly ash by partially replacing in cement from 0 to 50% and replacing river sand by quarry dust (0-50%) for various mixes.
During the tenure of the study, some physical and engineering properties of quarry dust and sand were determined and compared. The compressive strength of concrete was determined after replacing sand with quarry dust in various ratios. The results of the study showed encouraging results for replacement of 50% of sand with quarry dust.
Quarry dust The basic tests on quarry dust were conducted as per IS-383-1987 and its specific gravity was around 1.95. 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%. Coarse aggregate replacement of sand with quarry dust of mortar cube (C
