Optimization of Binary Mixes for Ultra High Strength Concrete by Puntke Method

Abstract

Ultra-high-strength concrete is a progression of high-strength concrete in concrete technology. It groups compressive strength of 150MPa or above. Since UHSC is another kind of solid, it has not been broadly utilized by the designers. Because of absence of research, it has just been utilized as a part of some reinforced concrete members and few large and precise structures. Research are been led to discover mechanical properties of UHSC utilizing distinctive mineral and synthetic admixtures. In our test, we centered to discover the ideal extent of mineral admixture with cement to accomplish most extreme packing density and make a mix design based on the obtained results. We have utilized five mineral admixtures as a pozzolanic material in cement. The mineral admixtures utilized were Quartz powder, Fly ash, Metakaolin, Ultra-fine slag and Rice-husk ash. A third generation superplasticizer was additionally utilized ito set up the mix design with a specific end goal to minimize the water necessity for cement hydration. The trial work is done in two stages. The main stage incorporates finding of different properties of materials like speceific gravity and water retention.The second stage incorporates optimization of binary blend by accomplishing greatest packing density utilizing strategy given by Puntke. After the analyses utilizing diverse materials, graphical portrayal was done to acquire the advanced extent. After the experiments using different materials, graphical representation was done to obtain the optimized proportion
