Preliminary Investigation on Self-Compacting Concrete Using Stone Dust and Fly Ash as Partial Replacement of Fine Aggregate

I. Sowmya | A. Roopa | P. Ukesh Praveen


Abstract: Concrete technology has made significant advances in recent years which results in economical improvement of the strength of concrete. This economical development depends upon the intelligent use of the locally available materials [1]. Important constituent of self-compacting concrete (SCC) is natural sand and filler material which is expensive and scarce. This necessitates that a suitable substitute be found. The cheapest substitute for natural sand is quarry dust and for filler material is fly ash. Quarry dust, a by-product from the crushing process during quarrying activities is one of the materials being studied and fly ash is a artificial pozzolanic material, a finely divided pozzolana form compounds which have cementitious properties, when mixed with hydrated lime and alkalies [4]. . In this work, the fresh and compressive strength properties of self-compacting concrete when the sand is partially replaced with stone dust, when the filler materials is increased by adding fly ash in % of the total powder content and when both substituents are implemented simultaneously. Optimization of stone dust and fly ash is also obtained. The results indicated that the incorporation of quarry dust into the self-compacting Concrete mix as partial replacement material to natural sand resulted in higher compressive strength and optimization of sand replacement is 40 %. Optimization of addition of fly ash in total powder content is 30 %.
