The article presents the outcomes of experimental research on reinforcement voltage loss caused by creep of autoclaved aerated concrete for the preliminary stressed aerated members. It has been stated that the losses have linear dependence on the initial level of reduction in aerated concrete in the scope of 0.30 to 0.60 Rbn, and the possible losses are 22-30%. The residual stress in prestressed reinforcement is in the scope from 117 to 245 MPa, which is sufficient for providing operating cracking resistance of large size items made of autoclaved aerated concrete under the conditions of moisture exchange and carbonizing processes. The obtained results are crucial for the further method of evaluating voltage loss caused by creep and preparation of practical recommendations on designing large size prestressed cellular-concrete items.
