• Abstract:

  The influence of the moisture content of the mature expanded clay concrete on its structural-strain characteristics is presented in this paper. On that base the critical stresses in the examined concrete are determined as well. The strain tests were made for six moisture states of the concrete i.e., the dry state, the full saturation state and four intermediate ones. It was found that the microcracking process starts earlier in the dry concrete than in the water saturated one; on the other hand, the process of the loss of the internal stability occurs earlier, at the lower stress, in the water saturated concrete than in one with smaller moisture content.
