Abstract

Recently, free form architecture has become an index for national competitiveness, and there has been a growing proportion of its design. Free form architecture having curved shapes require higher flexural strength than normal concrete. LMC that uses SBR latex suppresses cracking, improves adhesive force, and enhances flexural strength and tensile strength. Therefore, a common method for improving panel quality is to use LMC mixed with SBR latex in concrete. In this study, strength, absorption rate and fluidity tests were conducted with five mixing ratios considering the moisture contained within latex to find the optimal SBR latex mixing ratio. The optimal SBR latex mixing rate found through each experiment was 9%, and panels were produced using this. Afterwards, margin of error was verified through scans. Results of the verification showed that when adding SBR latex, flexural strength and quality of free form panels produced using normal concrete improved. By increasing the mixing rate of SBR latex to more than 9% in the future, it is predicted that higher flexural strength and compressive strength can be obtained. Such additional research is expected to be actively utilized in free form panel production technologies using SBR latex.
