摘　　要：In this paper,the macro properties and hy-dration phases of lime-sand silicate concrete which NaOH of various contents are added are studied by means of XRD. SEM etc. The results reveal that the addition of NaOH greatly increases the alkalinity of the concrete and have little influence on compressive strength of the concrete, the re-sults also show that the addition of NaOH promotes the for-mation of low alkaline hydrous calcium silicates but inhibits the formation of high-alkaline hydrous calcium silcates in the concrete.In this paper,the macro properties and hy-dration phases of lime-sand silicate concrete which NaOH of various contents are added are studied by means of XRD.
