Strength Developments and Deformation Characteristics of MMA-Modified Vinyl Ester Polymer Concrete

초록

This study investigated the strength developments and deformation characteristics of methyl methacrylate (MMA)modified vinyl ester polymer concrete, with MMA contents and curing temperatures as test variables. To lower the viscosity of the vinyl ester resin applied as a binder, an MMA monomer was added. In this study, the developed 168-h compressive and flexural strengths were 43.8-77.2 and 18.2-21.8 MPa, respectively. Also, these values decreased as MMA contents increased and curing temperatures decreased. The coefficient of thermal expansion ranged from 10.82 x 10(-6) to 14.23 x 10(-6)/degrees C, and it decreased as an MMA content increased. The ultimate compressive strain ranged from 0.00391 to 0.00494, which decreased with an increase in MMA contents and notably decreased with a decrease in curing temperatures. The modulus of elasticity tended to decrease as MMA contents increased and curing temperatures decreased.
