In order to make up for the shortage of natural sand, cobblestones are used for producing building sand in many places, but piling up of coarse sand, which is a screen residue in the process of producing the building sand by the cobblestones, needs to occupy a large amount of land, and if a coarse sand warehouse is designed and managed poorly, not only dust is easy to fly to pollute air quality, but also the coarse sand warehouse is easy to flow to a river channel and block the river channel, so that water quality is polluted. Therefore, while the shortage of natural sand resources is relieved, research on how to reasonably and effectively utilize the crude sand is needed, so that the crude sand is changed into valuable, and the problems of low resource utilization rate, environmental pollution and potential safety hazard are solved.
Therefore, the development of a common dry-mixed waterproof mortar is a problem to be solved urgently at present.
