Abstract
With the accelerated development of land desertification, sudden wind sand disaster, strong dust storm occurrence frequency more and more high.In the desert area where the alkali content in soil is low and there is existence of quicksand, the sand brick was prepared by using sodium silicate as chemical sand fixation adhesive materials and sodium fluosilicate as hardening agent, in order to improve the surface properties of desert land, control the spread of deserts and improve the environment of desert. In this paper, the suitable dosage of sodium fluosilicate and sodium silicate were studied,which have an important effect on compressive strength, flexural strength, block antifreeze and water absorption properties of the mortar test block.
