Optimization of Compression Strength by Granulometry and Change of Binder Rates in Epoxy and Polyester Resin Concrete

ABSTRACT: Polymer concretes are composite materials comprised of two or more different materials. The fillers are compounds such as resin, hardener, accelerator, colorant, or matrix structure reinforcing materials. When it is considered as a building component for the body of a machine tool, machine or application, different compounds are prepared for the target application. By means of an appropriate design, production and tests that can resist the working conditions, it is possible for any composite to obtain the desired result. For this purpose, it is necessary to determine many mechanical properties. The pressure strength is therefore a basic feature to know. Within the framework of this study, the change in pressure strength was elaborated on the basis of the different aggregate distribution and binder rates designed on the standard cement granulometric curves. The used binders and fillers were polyester and epoxy resin and quartz respectively. The results comply with the literature, and it was found that an appropriate mixture optimization is possible for the desired strength.
