Abstract

The invention discloses a method for preparing a grouting material, and belongs to the field of building materials. Calcium carbide slag is used as an additive to improve the performances of fly ash,the calcium carbide slag and the fly ash are melted at a high temperature to achieve full melting in order to improve the grouting rate of the grouting material and shorten the grouting time; the obtained melt is mixed with vermiculite and boehmite, the water absorption expansion performance of the vermiculite improves the grouting effect, an ion channel formed between the vermiculite and boehmitemakes calcium ions in the obtained molten mixture exchange and flow in order to promote the activity and shorten the curing time, and the properties of boehmite are used to increase the flowability and the permeability of the grouting material; and the obtained mixture is then mixed with an assistant, sepiolite and the like, the water absorption expansion performance of the sepiolite makes the sepiolite become soft, and the added assistant excites the solidifying performance of the grouting material, so the problems of long setting period and poor fluidity off existing cement-based grouting materials are solved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a preparation method of a grouting material. Background technique [0002] According to the method of ordinary cement mortar pouring, it usually takes more than 7 days of curing before it can be put into use. Metallurgy, chemical industry, electric power, building materials, railways, highways, bridges and other construction and equipment reinforcement anchorage and foundation grouting are often limited by the hardening and curing time of the secondary pouring of the concrete foundation. The early high-strength grouting materials are mainly composed of organic epoxy resins, which are expensive, easy to age, and highly toxic, and the effect is not ideal. [0003] In today's rapid development, rail transit has become the mainstream means of transportation, especially urban rail transit, and rail transit is now basically using ballastless track technology for construct...
