The Mechanical Properties of Polymer-Mortar Composites

Abstract

The polymer-mortar composites have several benefits, including corrosion resistance, high strength and modulus values compared to their low density, acceptable deformability, tailored design and excellent formability. This enables the fabrication of new elements and the structural rehabilitation of the existing parts made of traditional materials. In this work two sets of mixtures were prepared that consist of mortar and polymer to fabricate the polymer-mortar composite. The first set include mortar with ratio (1:1) (cement-sand) without water, while the other set include mortar with ratio (1:2) (cement-sand) without water. The polymer was epoxy which is added to the mortar after mixing the resin with the hardener in proportion of (1:3). Each set consists of different percentage of polymer (50:50, 40:60 and 30:70). to obtain Several results were obtained such as density, were the highest value was about 1906.4 kg/m3 for (1:1). The behavior of non-destructive test (UPV) was differ from that of density were the highest value was about 3521.12 m/sec for (1:2). The highest hardness of composites was 98.2 for (1:1). The destructive tests as compressive and flexural strength, the highest compressive strength was about 102.889MPa and the highest value of flexural strength was about 57.648MPa for (1:1).
