Study on Phenolic resin Modified Magnesium Oxychloride Cement

摘要

The influences of phenolic resin on the properties of both Magnesium oxychloride cement (MOC) pastes and MOC abrasive tools were investigated in this study. By incorporating phenolic resin in the MOC pastes, With 5% phenolic resin, the compressive strength of MOC paste decreased by 26%, the flexural strength of MOC pastes decreased by 21%, the abrasion loss of MOC abrasive tools decreased by 37%, the strength softening coefficient greatly increased. The mechanism maybe due to the microstructure of the MOC pastes became more compact with phenolic resin adding, the rate of hydrolyzation reaction of MOC phases would be postponed.
