This article presents the results of experimental research on the parameters of aerated concrete porosity strength properties and properties based on industrial waste. The structurally optimal amount of water was determined, reflecting the physical-mechanical, thermal-technical properties of the outer wall structures based on aerated concrete. The test results were carried out in research laboratories using aerated block constructions with high porosity and optimal composition, and improved technological solutions for autoclaved aerated concrete were developed. Study of changes in the properties of aerated concrete with the addition of waste quartz sand and steel smelting slag; optimization of aerated concrete composition by mathematical regression method and determination of physical and mechanical properties; the results of the research on automating the calculation of the proposed composition of aerated concrete and the amount of industrial waste according to its brand are given.

This article presents the modern state of energy-efficient residential building exterior wall constructions from aerated concrete, and the main properties of aerated concrete are analyzed. Properties of composite building materials, strength, and heat-technical properties depending on their structure are considered. Also, the analysis of existing problems in obtaining aerated concrete in the Republic of Uzbekistan is presented. The results of research on the use of industrial waste in aerated concrete have shown that it is appropriate to continue research using physical-mechanical and chemical activation methods for the wide application of secondary filler activation, particularly in construction production. The modern state of construction of external wall structures of energy-efficient residential buildings from aerated concrete is presented, in which the main properties of aerated concrete are analyzed. Properties of composite building materials, strength, and heat-technical properties depending on their structure are considered.

This article examines the road bridge over the Karadarya River on the 5th km of the exploited Andijan –Pakhtaabad route R135 Highway. In this case, the effect on the load-bearing capacity of its foundation on ShNQ 2.05.03-12, which is currently in effect, on the replacement of the bridge Intermediate Unit (highway bridge designed and built according to the temporary load classes N30 and NK-80, N10 and NG60) into the temporary load class A14 and NK-100, or on the load-bearing capacity of the Intermediate Unit in increasing its load capacity, was considered. Recommendations have also been made on the maximum increase in the class of permanent and temporary load falling on the foundation of this bridge, which is in operation.
