Abstract

The invention discloses a liquid fly ash material for road abutment back backfilling and a preparation process of the material. The liquid fly ash material comprises cement, fly ash, water and an additive, the mixing ratio of the cement to the fly ash to the water to the additive is (10-20): (80-90): (30-40): (0.1-0.2), and the content of the additive is 1% of the content of the cement; when the liquid fly ash material is prepared, the cement, the water, the fly ash and the additive are weighed according to the proportion; the cement, fly ash, water and additive are mixed to obtain a fly ash-water-cement mixture; the fly ash-water-cement mixture is stirred to prepare a liquid fly ash material; by presetting the falling speed and position of the raw materials, the powder can be quickly and uniformly mixed with water, the subsequent stirring and mixing time is shortened, and the preparation speed of the liquid fly ash material is increased.

Description

technical field

[0001] The invention relates to the technical field of building materials, in particular to a liquid fly ash material used for backfilling of highway abutments and a preparation process thereof. Background technique

[0002] At present, in highway, bridge abutment, culvert and other projects, using traditional backfill materials such as lime soil, water stability and other materials, not only the construction process is complicated, the quality of each process is difficult to guarantee, but also its strength is low, the stiffness is small, and the compressibility is relatively high. Large; after backfilling, with the increase of time, the settlement at the back of the platform is relatively large, and a wrong platform is formed at the back of the platform.

[0003] The existing plain soil, lime soil, stone powder and stone chips are mixed according to a certain proportion, and after being compacted or rolled into shape, it is difficult to achieve high strengt...
