CARBONATION PERFORMANCE OF CONCRETE MADE WITH NANOSILICA

The use of statistical analysis in this study facilitated in understanding the carbonation behavior of different concrete mixes with nanosilica. In the present work, a factorial analysis of variance (ANOVA) with two different cement types i.e. OPC and PPC and three different water-cement ratios as replicates was carried out. The results of the a fore said analysis with water-cement ratio as replicate showed that the nano silica have significant effecting overning the carbonation depth as compared to that of other above-mentioned variables. Cement types as replicates, nanosilica and water-cement ratio were recognized as the significant factor influencing the carbonation depth
