Abstract: As a result of the less foam quantities and better film-forming properties of emulsifier-free latex (FL) compared with conventional latex (CL), studies focusing on FL modified mortars are becoming increasingly important. Until now, few studies have reported the results about the pore structure together with mechanical properties of FL modified sulphoaluminate cement mortars. The aim of this work is to investigate the pore structure and mechanical properties of FL modified sulphoaluminate cement mortars. The results obtained have been compared with that of CL modified sulphoaluminate cement mortars, which allows us to analyze the effect of different latices on pore structure and mechanical properties of sulphoaluminate cement mortars.
Mercury intrusion porosimetry has been performed to investigate the pore structure and total porosity. The experimental results indicate that the total porosity of CL-modified mortars is higher than that of FL-modified mortars; the mechanical strength of FL-modified mortars is higher than that of CL-modified mortars except the flexural strength of a CL-modified mortar with a polymer/cement ratio of 15%.
