Accelerated climatic tests of extruded composites based on UHMWPE have been carried out. It has been established that stearic acid, used as a plasticizer, is washed out when exposed to climatic factors. At the same time, a significant degradation of the physical and mechanical characteristics of materials is observed. It has also been shown that the addition of a CO-4 stabilizer as an antioxidant improves the climatic resistance of materials based on UHMWPE, however, their fluidity and extrudability noticeably worsen.

The possibility of using construction materials based on sulfur binder, as well as a brief description of sulfur and physical and mechanical properties of samples based on it from local mineral raw materials are presented. Experiment is described and data of experimental studies of samples-cubes from concrete on sulfur binder are presented.
