The article proposes a unified structural approach to the use of shotcrete technology in construction from the point of view of cluster analysis. It is proposed to consider the shotcrete technology as a cluster with multilevel capabilities. A method of clustering the shotcrete technology has been developed, its main clusters and their parameters have been determined. The clustering algorithm of shotcrete technology is presented.

One of the most important tasks of construction is the use of energy-efficient single-layer structures based on foam concrete and an increase in their bearing capacity due to the use of fiber reinforcement, which will significantly improve the performance properties of fiber-reinforced concrete. Strength characteristics of fibro-foam concrete reinforced with polyamide granules with various types of filler and recommendations for its use in building structures were obtained. These experimental studies allow us to recommend the optimal composition of polyamide concrete compositions.Канд. техн. наук, доцент кафедры «Промышленное и гражданское строительство» Балаковский инженернотехнологический институт -филиал ФГАОУ ВО «Национальный исследовательский ядерный университет «МИФИ»
