The article presents the results of a study on foam concentration for the production of foam concrete using a two-stage foam introduction method. The research was conducted by evaluating the strength and density of foam concrete samples manufactured using both the proposed and conventional methods. ...

This study addresses the challenges associated with the accumulation of technogenic waste in the production of ferrous and non-ferrous metals. We present the findings of global research on the utilization of blast furnace slag as a sustainable alternative to traditional cement binders. Our...

The paper deals with influence anisotropy to shear strength of clay and differences in test results of shear strength parameters, cohesion (c) and internal friction angle (φ) considering the direction of testing. Clay is very often the foundation soil of many buildings. There were performed three...

The study investigates the enhancement of road infrastructure in the Center-South transport corridor of the Akchatau-Akzhal section, addressing the challenges posed by rapid road pavement deterioration due to increased traffic flow. By analyzing the natural and climatic conditions of the area,...

This paper considers the main problems of operation of metal gas discharge pipes on the example of research and survey work on the examination of building structures of the exhaust tower with three gas discharge trunks 180 m high, flue gas purification unit of the sintering shop of LLP "NDFZ" in...

The research investigates the transformative potential of fly ash, an industrial byproduct, in enhancing concrete compressive strength and addressing environmental concerns associated with its disposal. The study employs a rich dataset from Mendeley Data, comprising 471 data points, to...

This study presents an in-depth analysis of the pore structure in foam concrete, manufactured using a novel two-stage foam introduction method, with a comparative assessment against traditional foam concrete. Pore structure evaluation was conducted through visual-instrumental inspection and...

This paper deals with the problem of constructing new buildings in old urban areas, with emphasis on determining the actual dimensions of the active footprint of existing foundations. The study focuses on the problems associated with limited space for construction, geotechnical conditions, soil...

Обоснована актуальность темы исследования и дан краткий обзор разработанных ранее методов оценки влияния параметров транспортных сетей городов на характеристики транспортных потоков. Приведены полученные в результате исследований закономерности изменения скорости транспортных потоков в городах....

This study focuses on optimizing the design of a domestic centrifugal pump through the Taguchi method, aiming to enhance its performance. Experimental data on pump performance, including total head, efficiency, and suction specific speed, were collected and analyzed. The effects of three design...

The use of industrial waste in the production of building materials is an urgent task at present. Studies on the use of mineral wool waste in the manufacture of ceramic bricks have been carried out. For the preparation of experimental samples of ceramic bricks used clay deposit, as heaters and...

This study presents the control test process to assess the bearing capacity, crack resistance, and crack opening width of the volume block ceiling slabs and the floor slab of the inter-block corridor. These parameters play an important role in ensuring the reliability and durability of buildings,...

The article presents a method of production of foam concrete, which involves two-stage injection of foam. The proposed method involves improving the pore structure of foam concrete, due to a more uniform distribution of pores throughout the volume of the material. Laboratory tests were carried out...

The article considers the application of geotechnical interpolation using ArcGIS software to determine the intermediate geotechnical properties of soils at a construction site in a residential complex in Astana, Esil district. The study is based on data from 8 boreholes drilled to a depth of 26...

The Strip-Plot Design (SPD) is plays an important role in the complete block designs and also using the agricultural, medical and industry fields. SPD is best suited for a two-factor experiment that has more treatments than can be accommodated by a complete block design. In a SPD, one factor is...

When all experimental runs cannot be done under homogeneous conditions, blocking can be utilized to increase the power for testing treatment effects. In many real-life environments, there is at least one factor that is hard to change, leading to a split-plot structure. This paper demonstrates how...

When designing new systems and components, it is very important to correctly determine the degree and ability of the joint to withstand stress and load. Every new product that is intended for the market must meet the requirements for high safety and reliability during the entire life cycle. The...

This paper presents a reliability modelling of a two-unit ammonia/urea plant. Real maintenance data of the production plant have been used for this purpose. Four types of failure were noted: process, electrical, mechanical and instrumental failures. Both ammonia/urea formation units work in...

Рассмотрена проблема формирования окружающего пространства без барьеров для детей с ограниченными возможностями.
