Abstract
The present study is an experimental study to investigate the characteristics of strength by mixing polyaluminum chloride(PAC) with OPC-slag-FA ternary blended cement. There are three types of binders: 80% OPC + 10% slag + 10% FA, 60% OPC + 20% slag + 20% FA, and 40% OPC + 30% slag + 30% FA. PACs used 0, 2, 4, 6, 8, and 10% of the mixing-water weight. Experimental results show that PAC improves compressive strength regardless of the amount of OPC. PAC consumes portlandite, forms Friedel's salt, and reduces the diameter of the pores, making the matrix compact, contributing to the improvement of compressive strength. However, porous FA particles had an effect of delaying hydration by absorbing PAC in the initial hydration step. Therefore, the use of FA needs to determine the substitution rate in consideration of the hydration delay effect.
