Progress of Research and Application of Tuff in Cement and Concrete
As a common volcanic rock,tuff can be used as cement raw material,concrete gravel aggregate and admixture,which can not only alleviate the shortage of raw material supply for cement and concrete in the region and reduce the production cost,but also save natural re-sources and protect the environment.In this paper,the geographic distribution and basic physical and chemical properties of tuff are reviewed,and the influence of tuff as cement raw material,cement mixing material,concrete sand and gravel aggregate and admixture on the performance of cement and concrete is analysed,as well as the reasonable application of technical ways,and the development direction of the comprehensive utilization of tuff in cement and concrete is also looked forward to.
