This article discusses the issues of determining the current movements of the Earth's surface by geodetic methods at the Zhambyl predictive geodynamic polygon. The article discusses the characteristics of predictive polygons in the Republic of Kazakhstan. The data of vertical movements of the Earth's surface on the territory of the Zhambyl geodynamic polygon are presented. The results of high-precision leveling for 2020 and 2022 are presented, which made it possible to plot vertical displacement graphs and analyze changes in the position of geodetic reference points. The analysis showed that in the study area there are slight vertical displacements from -0.01 to -0.06 mm/year, which do not exceed the allowable possible accumulation of measurement errors.

The effect of surfactants and water-cement ratio on abrasion resistance of hydraulic concrete are presented. A series of laboratory tests and field surveys of hydraulic structures were carried out to determine the effect of various factors on wear resistance of hydraulic concrete to abrasive effects. Studies were carried out by comparison of laboratory tests for abrasion of mortar and concrete. Sulfite-alcohol bard (SAB) was used as a hydrophilic surface-active additive and as a hydrophobic soap. Structural changes of properties were studied by electron microscopic analysis. The presence of dependencies of the abrasion of concrete on several factors was established: water-cement ratio and strength, the type of filler, the fineness of cement grinding, the age of the samples, the use of surfactant additives, and the method of laying.

The article discusses methods for reinforcing brickwork using composite materials, as well as using stainless steel threaded rods. These methods are not widely used in Kazakhstan due to the lack of a regulatory framework governing their use. Traditional amplification methods are effective, but in some cases they are not suitable for use. An example is the strengthening of the load-bearing structures of historical buildings, the determining factor of which is the preservation of the appearance. In this case, the use of the discussed methods may be a justified alternative.

The influence of saw waste from the extraction of natural shell stone from the Beineu deposit and chemical additives on the preservation of the properties of the concrete mixture is investigated. It was determined that when using the MasterRheobuild 5555 superplasticizer (1.6% of the binder weight or 6.75 kg/m3), the mobility of the concrete mixture is maintained for 2 hours, then its sharp decrease occurs and this is accompanied by a decrease in the volume of entrained air to 16%. The introduction of the Sika ViscoCrete 20HE KZ superplasticizer into the concrete mixture B35 in an amount of 1% of the binder weight or 4.20 kg / m3 prolongs the retention of mobility up to 4 hours 30 minutes and a decrease in the precipitation of the cone is accompanied by a decrease in the initial volume of entrained air to 7%. The research results have shown that in order to increase the preservation of concrete mixtures with superplasticizers, it is necessary first of all to select the components of "superplasticizer – cement - filler", which have good compatibility.
研究了贝纽矿开采天然贝壳石锯材废料和化学添加剂对混凝土混合料性能保存的影响。当使用MasterRheobuild 5555高效减水剂(粘结剂重量的1.6%或6.75 kg/m3)时，混凝土混合料的流动性保持2小时，然后流动性急剧下降，同时携带的空气体积减少到16%。在B35混凝土混合料中加入西卡粘胶混凝土20HE KZ高效减水剂，用量为粘结剂重量的1%，即4.20 kg / m3，可延长流动性保持时间达4小时30分钟，锥体沉淀的减少伴随着初始携带空气体积的减少至7%。研究结果表明，为了提高掺有高效减水剂的混凝土配合比的保存性，首先要选择具有良好相容性的“高效减水剂-水泥-填料”组份。

In this article, an optimal dynamic synthesis of lever mechanisms was created and, on its basis, a dynamic synthesis of the mechanism of vibrational excitation of pulsed impact on the foundation was developed. An analytical-optimization method has been developed that allows, by introducing a modified objective function, to also determine the optimal dimensions of the mechanism links. Since the geometrical dimensions of the mechanism enter the objective function non-linearly (implicitly through the angles of rotation of the links, analogs of velocities and analogs of accelerations), numerical optimization methods are used to find them. In this case, at each step of the descent to the minimum, the mass-inertial parameters of the mechanism are determined analytically.

The article deals with modern environmental problems related to global environmental pollution processes, current processes of environmental education formation and the creation of eco-architecture of school buildings. The formation of the ecoarchitecture of educational institutions is revealed on the examples of international best practices, their design and construction. At the same time, the issues of the formation of environmental education in Kazakhstan and the related new ecological approach in the design of educational institutions are highlighted. The first examples of the creation of eco-schools in Kazakhstan are analyzed from the point of view of the formation of their architecture as a whole, as well as environmental principles in the creation of their internal educational spaces.

This article presents the results of studies of energy-efficient wood concrete using ash Astana-Energy CHPP-2. It was found that the use of ash improves the adhesion of rice husks with cement and has a positive effect on the workability of the wood concrete mixture. The optimal ash content of lightweight concrete is 10%, since a further increase in its amount reduces strength by 30-41%. As a result the composition of energy-efficient wood concrete on rice husk for energy-efficient construction was obtained. It was also found that when rice husks are treated with chemical additives, the strength of its adhesion to cement stone changes, and when soaked in water at 40°C with the addition of liquid glass and urea, it increases by 40%.
