| Abstract: | In this paper,drying shrinkage test was used to study the influence of fly ash on shrinkage performance of cement-reproduction powder compound cementitious system and alkali-activated slag cementitious system.Results show that fly ash can significantly reduce the shrinkage performance of cement-reproduction powder compound cementitious system and alkali-activated slag cementitious system.The mechanism of reducing the shrinkage performance of different cementitious system by fly ash was analysed. |
