Physical Properties of Polyester Polymer Concrete Composite Using RCSS Fine Aggregate

Abstract:

For the recycling of rapid-cooled steel slag (RCSS), various specimens were prepared with the different replacement ratios of RCSS and the addition ratios of polymer binder. The physical properties of these specimens were then investigated by compressive strength test, flexural strength test, water absorption test, hot water resistance test, measurement of pore distribution and observation of micro-structures using scanning electron microscope(SEM). Results showed that compressive and flexural strength increased with the addition ratios of polymer binder and replacement ratios of RCSS, but those strengths decreased reversely when addition ratio of polymer binder and replacement ratio of RCSS were excessively high. By the hot water resistance test, the compressive strength and flexural strength decreased remarkably and total pore volume increased but bulk density decreased. SEM observation of structure before hot water resistance test revealed very compact infusion of structure but decomposition or thermal degradation appeared in polymer binder when observed after the hot water resistance test.
