Obtaining and characterization of the polymer concrete with fly ash

Abstract

The aim of this study is investigation of properties of polymer concrete with fly ash as filler for obtaining new composite building materials. Polymer concrete realized of epoxy resin, fly ash and crushed fine and coarse aggregates has been prepared for assessing the influence of fly ash and resin dosage over its properties. Density, microstructure, compressive strength, flexural strength and split tensile strength were studied for different combinations determined on the design of experiments concept. The experimental results confirm the possibility of using fly ash to produce polymer concrete at a potentially lower cost and without compromising its structural integrity. The use of fly ash as a filler in polymer concrete is very promising because it improves the physical properties of the material and particularly its compressive and flexural strength. © 2009 Asian Network for Scientific Information.
