Zusammenfassung:The invention discloses a preparation method and a spraying process of C40 inorganic coating anti-freezing concrete. The preparation method comprises the following steps: pouring sand and stones intoraw material bins for pre-homogenization, wherein the pre-homogenization time is 5-10 minutes, and the stirring speed is 5-10 r/min; stirring and mixing the pre-homogenized sand and stones in a forcedstirrer for 2 minutes at the stirring speed of 3-6 r/min; mixing, adding cement, fly ash, a polycarboxylate superplasticizer and water, stirring for 5 minutes, adding an XTHPA environment-friendly high-permeability inorganic crystal waterproofing agent, and stirring for 2 minutes at the stirring speed of 3-6 r/min to obtain a concrete test block; and maintaining the concrete test block in water for 28 days, and spraying an XTHPA environment-friendly high-permeability inorganic crystal waterproofing agent and an XTSS environment-friendly surface sealant. The inorganic coating and the outer inorganic coating are added,
