Study of Concrete Expansion Admixture and Its Application

This paper introduces the development of concrete expansion admixture .The component of concrete expansion admixture and solid rubbish expensive performance and application have been analyzed. The existing problems and future development of concrete expansion admixture are discussed. The results shaw that the concrete durability will be well improved through the healthy developing of the expansion admixture which can also make the way of the development of ecological building materials wider.
