Packing Density Improvement for Improving Strength of Cement Paste

Abstract:

To design a mix for high-strength concrete is not easy, one of the methods is to improve the packing density of the cementitious materials. To study the effect of packing density on strength, a comprehensive research program using superfine pulverized fuel ash and silica fume was carried out. Results showed that a high superfine pulverized fuel ash and silica fume ratios could result in a lower optimum W/CM ratio for maximum strength. Depth analysis illustrated that the optimum water film thickness for maximum strength is always at around 0.01 to 0.05 μm, regardless of the SPFA and SF ratios.
