Reinforced concrete compressed elements with a small eccentricity and methods for calculating their strength are considered. A method for determining the deformation of the longitudinal reinforcement furthest from the longitudinal force is proposed. At the same time, the use of a single formula for s is ensured during the transition from an alternating deformation plot to an unambiguous one. Empirical dependence is used to determine the height of the compressed zone, which avoids solving the quadratic equation. In elements with a small eccentricity, symmetrical reinforcement is used, for this case the equation of equilibrium of longitudinal forces is derived.

Ferrous metallurgy has been and remains one of the main types of production activities that enables humanity to extract, process and produce basic equipment for all types of activities. The growth of ore production as well as the reduction in world reserves of the raw material base have lead to the search for effective methods of processing and preparation of waste for metallurgical processing. The mining and metallurgical sector of the Republic of Kazakhstan, which has its an integrated mining and metallurgical complex with its own coal, iron ore, and energy base, uses iron ores from several deposits. It also includes ash and sludge storage tanks, which store valuable metallurgical waste, such as converter production sludge, rolling scale, and others, the use of which is hindered by the presence of certain harmful impurities in the composition (a rather high content of non-ferrous metals, especially zinc, a high content of oils, etc.). These valuable technological wastes require additional research that may contribute to their use as a charge or as iron-containing components of the charge. Based on the urgency of the tasks of dephosphorylation of iron ores and utilization of human-made waste (converter sludge and rolling scale), studies were conducted to try to eliminate existing problems. The results of the research work make it possible to obtain metals based on prepared pellets with a significantly low phosphorus content; this will enable the use of an oiled rolling scale and converter sludge for the production of a metalized product for steel smelting. The resulting metalized products make it possible to dispose of scale and converter sludge by 70%, and the degree of iron extraction exceeds existing methods by 1–3.5% (92.1–94% vs. 95.6%).

This article is devoted to the study of clay raw materials of South Kazakhstan region. In particular, the article presents the chemical and granulometric compositions, as well as the physical and technical properties of clays, for determination of a possible ways of using of fusible and bentonite clays of montmorillonite and colloidal composition for the further production of thermal insulating expanded clays. During the research, the selected clay samples were subjected to modern physicochemical studies, in particular chemical, granulometric, scanning electron microscopic, differential thermal and X-ray phase studies. Based on the results of physicochemical studies, it was established that the clay of the Badam deposit is finely dispersed, the sum of the main compounds SiO2, Al2O3, Fe2O3 is 80.61-84.29% and is represented by a number of minerals - montmorillonite, sodium feldspar and hydromica.
