Combined with the research status of crop straws, and the comprehensive utilization of crop straws and the existing problems in Jilin Province, China. This paper proposes to crop straws to be used as the insulation materials of the precast concrete sandwich wall, which can’t only settle the problem of the lower utilization of crop straws, but also accelerate the development of the precast concrete structure in our country. Based on the research status of crop straws materials at home and abroad, the article summarizes the manufacture methods of crop straws as the insulation materials of precast concrete sandwich Wall. I hope that this article can provide valuable reference to speed up the comprehensive utilization of crop straws, and accelerate the process of building industrialization in Jilin province.
