CHOICE THEORY OF CREEP DEFORMATION FOR EVALUATION OF LONG FINE-GRAINED AUTOCLAVED AERATED CONCRETE IN VIEW OF FACTORS CARBONIZATION

Abstract

Experimental data on the effect of the age of autoclaved aerated concrete with and without carbonation factor to change its physical and mechanical characteristics, as well as by the amount of creep deformation and degree of reversibility. It was found that the solution of applied problems creep theory for structures of autoclaved aerated concrete, in accordance with their carbonation from the effects of atmospheric carbon dioxide, it is necessary to use the theory of elastic-creeping body on the basis of function creep measures in the form proposed by prof. S.V. Alexandrovsky.
