Also, the use of quarry dust as the fine aggregate decreases the cost of concrete production in terms of the partial replacement for natural river sand. Design mix of M25grade concrete with ...

Because of the lower specific gravity, the former absorbs more water than the latter, as illustrated by increased water absorption. Some of the previous works with …

Eighty four (84) of laterite-quarry dust concrete cubes of 150mm, eighty four (84) of laterite-quarry dust beams of 600 x 150 x 150mm, and for the purpose of comparison nine (9) of river sand ...

In this investigation, fly ash was substituted for the fine combination of Quarry Dust and cement. Partially substituting Fly Ash for Cement at 0%, 5%, 10%, …

Water absorption capacity of quarry dust samples from the study area ranged from 0.75 to 1.21% with an average value of 0.96%. Values of specific gravity tests ranged from 2.45 to 2.66 with an ...

The blocks comprised of different percentages of laterite soil (76%, 81%, 85% and 87%), quarry dust (9% and 10% by weight of the soil) and ordinary Portland cement (3%, 5%, 10% and 15% by weight of the soil. The results showed that cement content of 10% and 9% quarry dust was suitable for the block at any curing period above 7 days.

This is part of a research on the structural characteristics of concrete using lateritic sand and quarry dust as fine aggregate. ... laterite: 50% quarry dust and 1.67N/mm 2 for 25% laterite: 75% ...

Since lateritic sand and quarry dust are waste in environment they can be disposed by using in structural concrete. Lateritic sand and quarry dust were varied at different proportions. Fig 3. Flexural strength of concrete mixes for 28 days curing in N/mm2. Trial mix design was carried out for different W/C ratios.

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 construction industry of Sri Lanka expects a serious shortage of sand in the near future due to over exploitation of river sand. Then, the entire construction industry will be paralyzed if there are no alternative sources instead of river sand. Near-shore marine sand, dune sand and quarry dust (crushed rocks) are the other alternative sources …

concluded that the quarry dust can be used as a replacement for fine aggregate. It is found that 40% replacement of fine aggregate by quarry dust gives maximum result in strength than normal concrete and then decreases from 50%. The compressive strength is quantified for varying percentage and grades of concrete by replacement of sand with ...

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.
