The main application of polymer cements at that time was in concrete repair. The function of the polymer was mainly to reduce concrete permeability and to increase resistance to chloride penetration, toughness and adhesion. There are a number of polymer (monomer) types that are used in the modification of Portland cement paste. In this work sets of mixtures were prepared that consist of mortar and polymer to fabricate the composite. The sets include mortar with ratio (1:1) (cement-sand) without water, and the other 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 (1:2). Set consists of different percentage of polymer (50:50, 40:60 and 30:70)to obtain results such as density, were the highest value was about 1963.2 kg/m3 for (1:1).The behavior of non-destructive test (UPV) was differing from that of density were the highest value was about 3478 m/sec for (50:50) polymer-mortar composite ratio with (1:2) cement to sand ratio. The highest hardness of composites was 98.967 for (1:1). The destructive tests as compressive and flexural strength, the highest compressive strength was about 85.8896MPa and the highest value of flexural strength was about 45.888MPa for (1:1).When post-curing all results were increased except that for hardness it was decreased.
