The article discusses the properties of cement stone with the use of complex chemical additives to improve the technology for the production of sleepers from prestressed concrete. With the use of superplasticizer, the volume of intergranular space and, consequently, capillary porosity, which is a determining factor for both strength and frost resistance and corrosion resistance of concrete, are significantly reduced. Also, during thermo-wet processing, at a temperature of 40 ° C, there was no decrease in the strength of cement stone and sufficient strength at the initial stage of the curing period, 36 MPa with the addition of Glenium 27 …

Journal of Tashkent Institute of Railway Engineers
The article notes that at present, with the development of the construction industry, the need for fire-resistant concrete is also increasing. In increasing the volume of construction, concrete and other components are some of the resources available at the price of finished objects achieved through cost reduction. It is determined that the developed fire- and heat-resistant concrete, prepared according to the technological requirements developed by us and the established standards, will provide the facility with reliable fire safety and longevity
