The invention relates to the technical field of concrete protective materials and in particular relates to concrete protecting sol. The concrete protecting sol comprises the following components in parts by mass: 50-60 parts of a cementitious material, 5-10 parts of mineral powder, 2-6 parts of a nano cement additive, 10-20 parts of alkoxyl alkylsilane and a modified compound thereof, 1-8 parts of an air-leading and water-reducing agent, 0.3-1.2 parts of a water-retaining and thickening agent, 0.4-0.8 part of an expansion component, 0.3-1.2 parts of a macromolecular polymer, 0.2-0.8 part of a defoaming agent, 0.2-0.8 part of a wetting-dispersing agent, 0.5-0.8 part of a stabilizing agent, 2-10 parts of a modifying agent and 100-150 parts of deionized water. The concrete protecting sol has the beneficial effects that due to mixed use of the nano cement additive, alkoxyl alkylsilane and the modified compound thereof and the air-leading and water-reducing agent, the defect that gap compacting degree of concrete is low is overcome, and the penetrating agent alkoxyl alkysilane and the modified compound thereof can permeate into the concrete, a concrete structure is improved, and the defects that the concrete is cracked, strength is low and service life is short are fundamentally overcome.
