Abstract

The invention discloses a quick-setting early-strength geopolymer grouting material and a preparation method of same. The grouting material includes, by mass, 40-100 parts of a framework material, 0-20 parts of a doping framework material, 5-10 parts of an alkali activator, and 0.5-10 parts of a chemical additive. The grouting material has good durability, excellent groutability and short maintenance time, and is simple in preparation method.

Description

technical field [0001] The invention belongs to the field of highway maintenance, and relates to a fast-setting early-strength geopolymer grouting material and a preparation method thereof. Background technique [0002] From the perspective of my country’s energy background, there are still a large number of power plants in the country, which will bring a lot of waste—fly ash, and iron and steel smelters produce waste such as slime and slag. These wastes were often dumped wantonly in the past and are difficult to handle. Digestion. In addition, a large amount of energy is invested in the production of building materials in our country. In the continuous production process, there are problems such as energy conversion loss and waste discharge. Therefore, when we design products, we should take energy issues into consideration, that is, how to use materials that currently appear to be industrial waste as raw materials for product development, which not only solves the problem ...
