Comparative Analysis Between the Compressive Strength Properties of River Sand Concrete and Quarry Dust Concrete

Abstract
The construction industries in the developing world is looking for alternative materials that can replace the demand for natural sand, thereby reduce environmental load and waste management lost, reduction of production cost as well as augmenting the quality of concrete, and as such it becomes necessary that for a concrete to be used, its compressive strength has to be determined. So here comparison is made between the compressive strength of concrete made with river sand and that made with quarry dust as fine aggregate in the production of concrete. The selected materials were batched by weight and volume. The water-cement ratio was opted as 0.65 1:2:4 for mix ratio was selected for the experimental investigation, respectively. The specimens were cured for 7, 14, 21 and 28 days. For the purpose density and compressive strength tests were carried out. The river sand concrete showed better results and greater density and compressive strength than quarry dust concrete for all curing ages. The 28 days of curing, river sand concrete rise to 10.55 N/mm2, whereas quarry dust concrete was9.09 N/mm2. Both river sand concrete and quarry dust concrete has been found suitable for non-structural applications and lightly loaded members where high strength is not a prerequisite.
