Embodiment Construction

[0021] In order to further understand the content of the invention, features and effects of the present invention, the following examples are given hereby, and the details are as follows:

[0022] First of all, it needs to be explained that the micro-expansion medium-heat Portland cement in the present invention adopts the Chinese patent publication number CN103922618A, and the patent name is "a micro-expansion medium-heat Portland cement and its preparation method". Portland cement.

[0023] The specific preparation process of micro-expansion medium heat portland cement comprises the following steps:

[0024] 1) Raw meal preparation process: Limestone, sandstone ore waste rock, alumina red mud, fly ash, and iron ore stored in the raw material blending warehouse enter the raw meal mill according to a certain ratio. The raw material mill is the final grinding of the roller press, and the ground material is selected by the powder separator, and the finished product is put into ...

Abstract

The invention relates to a quick-setting high-strength anti-crack pavement patching material and a preparation method and application thereof, belonging to the technical field of cement production. The pavement patching material comprises the following raw materials in percentage by mass: 50 to 60% of micro-expansion moderate-heat Portland cement and sulphoaluminate cement, and 40 to 50% of auxiliary materials, wherein a mass ratio of the micro-expansion moderate-heat Portland cement to the sulphoaluminate cement is 1: (1-3); and the auxiliary materials are composed of the following raw materials in percentage by mass: 0.4 to 0.6% of fibers, 2.5% of rubber powder, 0.2% of a water reducing agent, 0.03% of a defoaming agent, 31 to 34% of fine sand and 8 to 11% of fly ash, and the proportionsof the fibers, the rubber powder, the water reducing agent, the defoaming agent, the fine sand and the fly ash are the percentages of the components based on the mass of the whole repair material. The quick-setting high-strength anti-cracking pavement patching material is prepared from the micro-expansion moderate-heat Portland cement, the sulphoaluminate cement and the auxiliary materials, so pavement patching cost is reduced, quick patching is realized, and obvious economic and social benefits are produced.

Description

technical field [0001] The invention belongs to the technical field of cement production, in particular to a fast-setting high-strength anti-crack pavement repair material and its preparation method and application. Background technique [0002] After the road has been in service for a long time, especially after frequent heavy vehicles, there will be many cracks, which will not only affect the use of the road, increase safety hazards, but also affect the overall appearance of the factory area. In response to this problem, our company has discussed two solutions, one is to renovate the road with cracks, and the other is to use high-strength crack-resistant quick repair material for repair. The way to renovate cracked roads is not only time-consuming and affects road use, but also very expensive. In order to solve the problem of road cracking, it is urgent to develop a fast-setting high-strength crack-resistant pavement repair material that can be quickly repaired, opened to...
