Prediction method for shrinkage deformation of steel slag concrete
The invention discloses a method for predicting shrinkage deformation of steel slag concrete, relates to the technical field of concrete, and aims to solve the problem of lack of a method for predicting shrinkage deformation of steel slag concrete in the prior art. Comprising the following steps: (1) obtaining a self-constriction value of concrete not doped with steel slag; calculating the equivalent bone-glue ratio of the steel slag concrete based on the elastic modulus of the steel slag aggregate and the natural aggregate by considering the limiting and restraining effect of the steel slag aggregate on concrete self-constriction; constructing a self-constriction prediction model of the steel slag concrete; (2) obtaining the drying shrinkage value of the concrete not doped with the steel slag; calculating the equivalent aggregate volume fraction of the steel slag concrete based on the elastic modulus of the steel slag aggregate and the natural aggregate by considering the limiting and restraining effect of the steel slag aggregate on the concrete drying shrinkage; constructing a drying shrinkage prediction model of the steel slag concrete; and (3) constructing a total shrinkage value prediction model of the steel slag concrete based on the self-shrinkage prediction model and the drying shrinkage prediction model of the steel slag concrete so as to predict the shrinkage deformation of the steel slag concrete.
