POLYMER MODIFIED CONCRETE. INCOMBUSTIBILITY OF POLYMER CONCRETES MADE WITH WET AGGREGATES

Polymer concretes using various polymeric binders are widely used as building materials, but it is generally considered that their thermal resistance and fire resistance are limited because of the thermally unstable and combustible polymeric binders used. This paper deals with the incombustibility of aggregates by applying strength improvement techniques, including the addition of moisture absorptive additives, a silane coupling agent, and steel fibers. It is concluded from test results that the use of wet aggregates causes a great deal of improvement in the incombustibility of polyester concrete, but polymethyl methacrylate concrete with wet aggregates does not provide a good incombustibility because of the thermal decomposition of its binder at a relatively low temperature.
