- 摘要：
The present invention relates to a method for producing a solidification snow removing material of a liquid calcium chloride snow removing material using expanded pearlite produced by heating perlite, wherein the expanded pearlite is heated after being mixed with any one selected from soil cement, peatmoss, zeolite, and vermiculite so that the expanded pearlite is modified. Water is removed from the fine pores of the modified expanded pearlite, and calcium chloride is absorbed in the fine pores, so that air permeability, water retention, and fertilizer retention are improved. The method comprises the following steps: mixing and heating expanded pearlite with any one modifying body selected from soil cement, peatmoss, zeolite, and vermiculite to be modified with the expanded pearlite (S110); injecting liquid calcium chloride to the expanded pearlite modified in step S110 (S120); and drying and cooling the expanded pearlite having the liquid calcium chloride injected therein to increase the concentration of
