Studying Specific Features of the Monolithic Construction Technology Based on Systemic Analysis

Abstract

A scientific study was conducted, the main goal of which is to improve the quality of the monolithic construction by grouping and systematizing the main characteristics of the monolithic construction technology, especially those that affect its safety and quality, as well as identifying the most important and unresolved problems affecting the security of monolithic reinforced concrete buildings and structures using systems analysis. To systematize the monitored quality indicators, a decision tree was developed. Based on the quality monitoring the construction sites, a grouping was carried out according to the nature of the violations and a chart was constructed showing the distribution of violations identified during the construction control of the construction organizations. The research and analysis of the scientific support of construction sites show that it is possible to obtain reliable results during quality control only by using several methods at the same time. Apart from that, the issue of choosing a method for testing concrete in the winter conditions still remains relevant. Even with a large number of papers being devoted to this issue, it needs a further research. The conducted system analysis showed that the main cause of defects in thr buildings and structures is the inability to provide the necessary characteristics of concrete both during the preparation of the concrete mix and during the construction phase of the finished monolithic structure. The research results allowed: to note the effect of production control on the quality properties of monolithic structures; identified the main causes of defects in buildings and structures at each stage of the monolithic construction, identified and justified the need to develop recommendations and experimental studies to improve production operations, including non-destructive testing methods for the strength of the monolithic structures.
