In modern society, as the volume of traffic has increased due to population growth and industrial development, the number of fires, which is caused artificially such as a car accident, has increased greatly. The damage on normal concretes and high performance concretes has become more serious that the countermeasure is on the problem is necessary. Recently, attempts to reduce the carbon dioxide emission, which is one of the major causes of global warming, is increasing. In particular, the concern for the cement production has risen as it produces great amount of carbon dioxide in the process. The amount of carbon dioxide released in the process of producing 1 ton of cement is 1 ton, and we need an effort to control and reduce the carbon dioxide emission by reducing the use of cement. This study aims to acquire excellent fire resistance efficiency and high physics, dynamics performance and develop environment friendly fireproof material. First, physical, mechanical property examination and fire resistance experiments, having the amount of PP fibers and type of lightweight aggregate as variables, were made to derive the optimal material of high strength refractory polymer mortar in the influence of material elements. The experiment consisted of compressive strength test, flexural strength test, chloride ion penetration test, thermal conductivity test, fire resistance test and to investigate the thermal properties of the aggregate, TGA analysis was conducted. The satisfying results were deduced showing the performances in all combinations and the combinations that showed the best fire resistance performance was the Pearlight combination. Second, the compressive strength and residual compressive strength (after the fire resistance test) tests, having the amount of slag, Porcelain, PP fibers as variables, were conducted to develop eco-friendly and high performance refractory materials in the optimal combination of high strength refractory polymer mortar. As a result of the experiment, the combination that consists of 100% slag and 0.1% PP fiber, 15% Porcelain showed the best performance and further experiments were conducted to compare the combination with conventional refractory cement. The result was that the eco-friendly fireproof high strength polymer cement composites showed better performance than conventional refractory cement.
