Journal Title: Вісник Одеської державної академії будівництва та архітектури - Year 2018, Vol 1, Issue 70
Abstract
The results of experimental research of microcracking and coefficient of tension intensity of experimental patterns from expanded clay lightweight concrete on multi-component binding and quartz sand are given. Optimal compositions of construction and heat insulation expanded clay lightweight concrete on multi-component binding are presented. Methodology of experimental researches, parameters of experimental patterns with the description of the technology of their production, results of basic patterns tests and their analysis, and also volume, aims and results of auxiliary standards tests are described. In the process of tests the longitudinal and transversal deformations of patterns, value of crack appearance loading, size of the destroying loading were measured. Conducted experimental researches of the limits of microcracking and coefficient of tension intensity of patterns from expanded clay lightweight concrete on multi-component binding allowed to find the characteristic features of their tensely-deformed state, to define the high and lower boundary of crack appearance, deformability and size of the destroying loading of experimental patterns.
