Concrete protecting sol

Abstract

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.

Description

Technical field [0001] The invention involves the field of concrete protection materials, especially a concrete protective solution. Background technique [0002] The investment in infrastructure of cement concrete construction in my country is huge, the maintenance costs are quite high, and the demand for repairing materials is also very large.At present, the protection of concrete structures mostly uses the method of coating protection materials on the outer surface of the concrete. In the osmotic material, such as the material with sodium silicate as the main ingredient, it can be coated or injected with silicon in the waterproof area and the maintenance site.The material of sodium acid is the main ingredient to achieve the purpose of protecting the concrete structure.However, the material has problems caused by sodium sodium silicate in the concrete, poor permeability, and poor penetration, and generating leather -shaped objects. [0003] The protection of concrete should be ...

Problems solved by technology

Usually concrete is composed of granular coarse aggregate, fine aggregate and cement hydrate. During the pouring process and use, due to various reasons, some quality problems often occur and affect its service life.

In the process of pouring and curing, due to cement hydration and water evaporation, it is easy to cause concrete cracking, resulting in poor concrete strength development

Moreover, in the application of concrete in actual engineering, it is often exposed to various harsh environments, such as the intrusion of corrosive media around the environment, changes in environmental temperature and humidity, freeze-thaw cycle damage, and some concrete projects are often subject to heavy load wear. External conditions will seriously affect the service life of concrete

Therefore, the use of a simple concrete curing agent is difficult to achieve the concrete protection function during pouring.
