Influence of powder and paste on flow properties of SCC

This paper presents the results of an experimental investigation carried out to find out the influence of paste and powder on self-compacting concrete mixtures. Tests have been conducted for 63 mixes with constant water content varying from 175 l/m3 to 210 l/m3 with three different paste contents. Among the different water contents and w/c ratios studied, for each series of experiments, w/c ratio and more importantly, water is kept constant. Slump flow, V funnel and J-ring tests were carried out to examine the performance of SCC. The results indicate that the flow properties of SCC increase with an increase in the paste volume.
