Abstract:Through the screening of raw materials,proportioning design and experiment,this paper developed a polymer edge-sealing mortar for the edge-sealing or segregation of the grouting layer of prefabricated concrete components. According to the requirements of ambient temperature,it is divided into normal temperature polymer edge-sealing mortar and low temperature polymer edge-sealing mortar. Its performance can meet the construction needs of summer and winter. The engineering application effect is good.
