The results of experimental research of microcrack appearance and coefficient of tension intensity of experimental patterns from ceramsite concrete on multicomponent binding and quartz sand are given. Optimal compositions of construction and heat insulation ceramsite concrete on multicomponent binding are presented. Methodology of experimental researches, parameters of experimental patterns with description of technology of their making, 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. The done experimental researches of limits of microcrack appearance and coefficient of tension intensity of patterns from ceramsite concrete on multicomponent binding allowed to educe the characteristic features of their tensely-deformed state, to define the high and lower bound of crack appearance, deformability and size of the destroying loading of experimental patterns.
