Jul 01, 2011· Research highlights Quarry dust (QD) used as partial substitute of sand, and RHA as cement replacement. QD obtained as a by-product from the crushing process of granites. RHA enhanced the hardened mechanical properties of concrete. Minor decline in mechanical properties were observed due to QD inclusion. QD can be a viable substitute to sand, in the presence of RHA to produce HSC.
Mar 31, 2020· Westend61/Westend61/Getty Images. The basic mix ratio for concrete is one part water, two parts cement and three parts sand. An alternative ratio is one part cement, two parts sand and three parts gravel with enough water added until the mixtures reaches the consistency of thick mud. Lime is also a common additive to the mix.
Apr 15, 2005· For soil cement the CRUSHED gravel should have poper mix of fines to larger pieces to make it as dense as possible. Add the proper amount of cement and water and mix well by some mechanical means, smooth to grade and pack it. The mix is not a slurry and is very hard to tell from damp gravel. A seal coat over the top will also help for longevity.
A mix of aggregate sizes will change things too. Very fine sand will require more cement in the mix, as the tiny particles have more surface area for the given volume, so more cement is needed to coat the sand for good adhesion. But fine sand is easier to mix, easier to work, easier to stuff into a place.
A. Mix proportioning 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 …

The cement or mortar is mixed by first adding a portion of the water. The sand and cement are then poured into the water, and the mixture is stirred for several minutes. More water, cement or sand can be added if the mixture is too wet or dry. Below is an example of a sand to cement mix ratio recommendation from a cement manufacturer.

In India the use of quarry dust to replace river sand was reported by [2]. The use of rock dust as an alternative to natural sand was also reported by [5]. The use of up to 20% quarry waste fine as a partial replacement for natural sand in the production of concrete, in Malaysia was also reported [6].
in percentage replacement of sand with quarry dust for the same w/c ratio. Concrete does not give adequate workability with increase of quarry dust. It can be due to the extra fineness of quarry dust (Jain et.al., 1999). Increased fineness require greater amount of water for the mix ingredients to get closer packing, results in
