Abstract: The effects of fly ash content on the setting time,compressive strength,chemical shrinkage and autogenous shrinkage of alkali-activated slag mortar were studied.The results show that the addition of fly ash can not only effectively improve the problem of rapid condensation and large shrinkage deformationof alkali-activated slag mortar,but also can solve the problems such as low early strength and slow strength development of alkali-activated fly ash mortar.With different content of fly ash,to seek the best content,to ensure that strength of alkali-activated slag mortar while reducing shrinkage effect.
