Research Review of Interactions between Alkali-activated Materials and Concrete Shrinkage
Alkali-activated materials have been widely applied in concrete technology.This paper comprehensively analyzes and generalizes the relationship between alkali-activated materials and the shrinkage characteristics of concrete.Firstly,alkali-activated materials'definition,classification,and mechanism are introduced.Then,the shrinkage characteristics of concrete are summarized,including shrinkage's definition,classification and its influence on the performance of concrete.By comprehensively analyzing the existing research results,the effects of alkali-activated materials on free shrinkage,dry shrinkage,hydration shrinkage,and temperature shrinkage are discussed,and the influencing factors are reviewed and investigated.Finally,the research results of the interaction between alkali-activated materials and concrete shrinkage are summarized,and the development direction of future research is proposed.
