Kata kunci: Resin Polyester, Beton Resin, KuatTekanBeton ABSTRACT Indonesia is a country that has a very rapid development rate from the era of President Soeharto to the current president. The role of the government as a development mobilizer is very strategic in supporting the improvement of people's welfare and the economic growth of their country. At present the need for infrastructure continues to increase along with the increase in economic activity. The use of concrete as a building material has long been known in Indonesia. Concrete has high compressive strength, is easy to adjust to the needs, low maintenance, and can utilize local materials. Even though, due to its brittle and practical nature it is unable to withstand good tensile forces, the material has limitations in its use. Along with the development of time, various innovations have been carried out to improve the performance of concrete so that there are terms such as low strength concrete (low strength concrete), low-strength concrete (medium strength concrete) and high-strength concrete. In this research, we tried to make a new innovation by applying polyester resin with the SHCP 2668 type as an added ingredient in a mixture of medium strength concrete. The variation of resins used were 7%, 8%, and 9%, respectively. The purpose of this addition is to find out the effect of adding polyester resin to the strength of concrete. The making of test specimens was carried out in the laboratory of the Yogyakarta National Institute of Technology and testing was carried out in the laboratory of Gadjah Mada University after soaking for 28 days. From the results of the strength test the concrete was obtained an average value of 20.75 MPa for normal concrete, 16.03 MPa for 7% resin concrete, 14.90 MPa for 8% resin concrete, and 12.64 MPa for 9% resin concrete. From the results of these tests it can be concluded that the addition of polyester resin to normal concrete results in a decrease in the strength value. Keywords: Polyester Resin, Concrete Resin, Concrete Compressive Strength
