Khomenko A. The development of deformation gradients under the local moistening of the building products

The object of research - local and integral deformations on different levels of soncrete and products structure; goal - accounting and controlling of the deformation gradients under the local and one-sided moistening of building products considering structural components of building materials; methods - graph-analytic and photoelasticity methods; measuring of shrinkage deformations with micrometers, value of division equals 0,001 mm; analytical description of the results performed with the method of the least standard deviation; results consist of developing the methods of predicting shrinkage deformations in heterogeneous materials with a directed creation of inner interfaces and and recommends about accounting inner interfaces while measuring local and integral deformations; introduced - for conducting technical surveys and overhauls of buildings and structures.
