Abstract

The invention discloses a novel inorganic waterproof plugging material and a preparation method thereof. The novel inorganic waterproof plugging material comprises fly coal ash, steel slag, slag, metakaolin, ordinary portland cement, sodium silicate and sodium hydroxide. The preparation method comprises the following steps that the sodium hydroxide is dissolved in water in accordance with a mix proportion, is added to sodium silicate after the sodium hydroxide is completely dissolved, and evenly stirred to obtain an alkali activator which keeps stand for 2h to be ready for use; and powder is added to a blender according to a mix proportion to be evenly mixed, the prepared alkali activator is added in accordance with a ratio to be stirred for 3min to obtain the novel inorganic waterproof plugging material which can be used for waterproofing and plugging of a building roof, a metope, a pipeline and other parts. Compared with the traditional inorganic waterproof plugging material taking cement as a main base material, the novel inorganic waterproof plugging material provided by the invention has the technical advantages of high strength in the early stage, good impermeability, freeze resistance, heat resistance and the like, a large number of industrial waste slag is utilized, the production process is environment-friendly, and the economic benefits and social benefits are good.

Description

Technical field [0001] The present invention is a waterproof material for building waterproofing, which involves a new type of inorganic waterproof material leakage material and their preparation methods. Background technique [0002] Building leakage is mainly manifested in walls, roofs, doors and windows, and pipelines. It is an important disease that affects the service life of modern concrete structures. How to effectively stop water to stop leakage is the current research hotspot.The existing waterproof and leakage materials are generally divided into two major categories: organic and inorganic models. Organic waterproof and leakage materials are easy to aging and used for the poor effect of waterproof and leakage of concrete structure.The material does not have aging problems. It can quickly solidify the surface of the concrete structure, low production cost, and good leakage effect. It is currently the main method of waterproofing of waterproof waterproofing.At present, th...
