(PDF) Concrete Compressive Strength Using River Sand and Quarry Dust

River sand was combined with quarry dust in five different ratios for each replacement level: 100:0, 90:10, 80:20, 70:30, 60:40, 50:50, and 0:100. For each blend, ten cubes of (150 x 150 x 150) mmIt was observed that sandstone cutting waste can be utilized in the production of structural concrete as partial replacement of river sand up to 10% replacement level using w/c ratio of 0.35 & up to 30% replacement level using w/c ratio of 0.4 & 0.45.

(PDF) QUARRY ROCK DUST AS A PARTIAL REPLACEMENT OF

Quarry Rock Dust (QRD), a by-product from crushing process during quarrying activities is one of the substitute materials for the natural river sand. In resent years there were many attempts haveIn such a scenario, the rock quarry dust or quarry dust can be an associate degree in order to replace partially or fully river sand. Quarry dust is formed as a waste material which is non-voluble, residue tailing fine particles having size less than 4.75 mm. These are produced during process of processing and extraction of course aggregates.Shear Strength of Rock Quarry Dust and Sand Mix

(PDF) USE OF STONE DUST AS AN ALTERNATIVE FINE

Stone dust is a by-product from rock crusher and it can be recycled by using it in the concrete and maintained the sustainability. As stone dust has acceptable properties of a fine aggregate sandThere is a shortage of river sand throughout the World and in Peshawar, Pakistan . To fulfill the growing demand for sand, an alternative material needs to be explored. Rock powder can be used as a substitution of natural river sand fully or partly . A huge quantity of stone powder is produced during the stone crushing process .Physical and mechanical characterization of sand replaced stone dust

Influence on compressive strength of concrete by partial replacement

The Fig. 4, shows that by replacing 25%, 50%, 75% and 100% replacement of river sand with FAGS. From the Fig. 4, it can be observed that the compressive strength with zero FAGS (i.e. only river sand) was 16.1 MPa which decreased to 14.5 MPa at 25% replacement, 17.7 MPa at 50% replacement. It reduced to nearly The enhancement in the compressive strength is reported due to the replacement of river sand with bottom ash, ferrochromium slag and copper slag in the concrete. Reduction in the workability was witnessed for the concrete attributed to the replacement of sand with granite dust, crushed rock, sandstone and marble dust as fine Cleaner production of concrete by using industrial by
