Compressive Strength of Nano-Silica Incorporated Recycled Aggregate Concrete

Abstract

The present work is based on analysis of the influence of incorporation of Nano-Silica on compressive strength of recycled aggregate concrete using two factorial designs. In this study, recycled coarse aggregate (%), Nano-silica (%) and Specimen Type are selected as factors and each having two levels. Four numbers of mixes with three replicates are designed and compressive strength at seven and 28 days are selected as responses. Analyses of Variance (ANOVA) of experimental results are carried out to study the influence of factors and various plots are used to demonstrate the results of the analysis. The outcome of the study depicts that the selected factors are significantly affecting the compressive strength of concrete. However, the analysis indicates that interaction of factors has no substantial influence on compressive strength of concrete.
