A study on the effects of compositions on the mechanical properties of polymer mixed concrete / Mohd Zuhairi Edaris

The purpose of this project is to study the effect of different compositions on the mechanical properties of Polymer Concrete. The polymer concrete in which we are concern with composes of sand, talcum powder and resin. The total amount of sand, talcum powder and resin for all compositions are equal to 3500g. The resin that we chose composes of Polyester and Hardener M-50. We changed the compositions by changing the amount of resin and sand. To study the mechanical properties of the composite, three tests were conducted, the tensile test, the impact test and the bending test. For each test, at least three specimens from the same composition were tested. For the tensile test conducted the composition gives a performance result in range of (479.7N - 824.4N). For a maximum tensile stress the result are (1.713Mpa - 2.944Mpa) and the increasing value of modulus elasticity from (340.279!Vlpa - 409712Mpa). For the bending test the increasing value of maximum bending stress from (2.43Mpa - 3.52Mpa). For a maximum bending strain the result are (0.025 - 0.035) and the modulus elasticity also showed the increasing value from (321.2Mpa - 397.5Mpa). For the impact test was conducted the result of the impact energy increasing from (2.74J - 2.96J).
