Recycled Concrete Sand PTY Ltd is a dynamic innovative company based in Cape Town South Africa. The reduction in the sources of natural sand and the requirement for reduction in the cost of concrete production has resulted in the increased need to identify substitute material to sand as fine aggregates in the production of concretes especially in Concrete.
780 IRACST Engineering Science and Technology An International Journal ESTIJ,ISSN 2250-3498 Vol. 3, No. 6, December 2013 The derivation gives clear picture that quarry dust can be utilized in concrete mixture as a quality substitute instead of river sand to a high strength at 50 replacement.
quarry dust, M 4 40 quarry dust, M 5 50 quarry dust respectively. The variations of slump value with quarry dust percentage are shown in Figureure 1. It is observed that the slump value increases with increase in percentage replacement of sand with quarry dust for the same wc ratio. Concrete does not give adequate
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.
May 05, 2017 Quarry dust can be used as an economic alternative to the natural sand. In this investigation an attempt is made to utilize quarry dust as a partial substitute for natural sand in producing concrete. Natural sand is replaced by Quarry dust at an interval of 5, 10, 15, 20 and 25. Mix proportions for M20 concrete is prepared with reference ...
3.4 Quarry Dust The quarry dust used for this investigation work is obtained from the quarry near tindivanam in Tamil Nadu. The quarry dust passing through 4.75 mm retained on 150 micron IS sieves are taken. Specific gravity of 2.617 and fineness modulus of 2.706 has been used. 3.5 Silica Fume The specific gravity of silica fume is 2.2.

Aug 23, 2019 Quarry dust can be partially used as an alternative to river sand, as fine aggregate in concrete production. It is basically a by-product of stone crushers produced during the crushing and screening process of coarse aggregates. The replacement of river sand with quarry dust enhances the compressive strength of the concrete to a limited extent.
