摘　　要：The numerical method and random anal- ysis of cement concreteexpansion are given. A mathematical procedure is presented whichincludes the nonlinear charac- teristis of the concrete. Anexpression is presented to pre- dict the linear restrained expansionof expansive concrete bar restrained by a steel rod. The resultsindicate a rapid change in strains and stresses within initial days,after which the change gradually decreases.The numerical method and random anal- ysis of cement concreteexpansion are given.
