About The Technology Of Making Reinforced Concrete Sleep By Heating Concrete At Low Temperature, Turgunbaev Urinbek Jamolovich, Movluda Umirova
Journal of Tashkent Institute of Railway Engineers
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 …
Problems Of The State Of The Rolling Surface Of The Rail Head On Speed And High-Speed Railway Sections Of Jsc "Uzbekistan Temir Yollari", Kuvandik Saginovich Lesov, Igor Ivanovich Kuznetsov, Mukhamedali Kazbek Ugli Kenjaliev, Xushnudbek Odilbekovich Samandarov

Journal of Tashkent Institute of Railway Engineers
In the process of train traffic on the rolling surface of the rail head are formed bumps and fatigue defects, constant dynamic loads lead to the frustration the upper structure of the path. In this article the analyzes integral indicators of the rolling surface of the rails (long waves, medium waves, short waves) on the section of speed and high-speed train traffic for assess the condition of rails in transit. Problems with the formation of wave-like irregularities on the surface of the rails are identified, promising directions in solving this problem are indicated.
