Rheology of self-compacting concrete nanocomposites

Abstract

In the current research work the fresh properties (filling and passing ability, and resistance to segregation of self-compacted concrete (SCC) are investigated with the nanocomposite particles. Under the scope of the research work, the rheological parameters of the fresh self-compacting concrete (SCC) fused with nano sized Blasting Grit (nBG) (average particle size 500 nm) and rod like Zinc Ash (nZA) (average particle size 300 nm) are analyzed. In the scope of the work nZA and nBG are fused in Pozzolana Portland Cement (PPC) and Fine Aggregate (FA) respectively, for 0%, 0.25%, 0.5% and 0.75% by weight of material. The rheological behavior of SCC like filling ability, passing ability and segregation resistance are studied for the modification in SCC. The result shows significance of the material and test method used in this experiment. The output of the experiment shows that the rate of fusing of nZA and nBG in ingredients of the concrete contributes in rheological and mechanical properties of SCC. For the validation of the experimental results the statistical models also prepared, the regression model, ANOVA model and Correlation model gives the importance of the ingredients used along with selected test for the work. The current research is useful for developing zinc ash and blasting grit as a building material. The outcomes of the experiments are more important in a fresh stage of the SCC which was developed as a sustainable way with the good flowing ability.
