Flexible Properties of MMA Modified Polymer Mortar
MMA 개질 폴리머 모르타르의 굳기전 성질
Abstract
In this study, methyl methacrylate (MMA) - modified polymer mortar(MMPM) was developed and its setting shrinkage and working life properties were surveyed. In order to study the setting shrinkage, setting shrinkage test for the 24 batches were also conducted with taking the MMA monomer content to the UP resin and the mixed content of shrinkage reducing agent(SRA) as variables. Furthermore, in order to study the working life measured gel time, working time, setting time of MMPM and binder. Experimental resurts show that the workability remarkably improved as the mixed MMA content increased. The working life was proportional to MEKPO content and was shorted. also, showed high interrelationship of binder gel time and MMPM working life. Setting shrinkage markedly reduced as the content of MMA and the SRA increased.
