Cement-based grouting treatment material and preparation method thereof

Abstract

The invention discloses a cement-based grouting treatment material, which comprises, by weight, 39.4-45.9 parts of cement, 26.0-33.9 parts of fly ash, 20.1-25.7 parts of water, 0.4-0.8 part of sodium sulfate, 0.02-0.03 part of triethanolamine, 4.0-5.0 parts of expanded perlite, 0.12-0.26 part of a polycarboxylic acid water reducer, and 0.01-0.05 part of a dispersing auxiliary agent. The invention further discloses a preparation method of the material. According to the present invention, the preparation method is simple, and the prepared grouting material can be grouted into the cavity position on the lower portion of the cement concrete panel by using the special facility, has characteristics of excellent fluidity, excellent workability, volume micro-expansibility, no generation of phenomena such as segregation, bleeding and the like, and low cost, can be rapidly condensed to form the high strength material, and can be widely used for the grouting treatment on the cavity disease of the cement concrete pavement.

Description

technical field [0001] The invention relates to the technical field of cement concrete pavement maintenance, in particular to a cement-based grouting treatment material and a preparation method thereof. Background technique [0002] Cement concrete pavement has the advantages of large bearing capacity, good stability, long service life, and low daily maintenance costs. It has long been one of the main types of high-grade, heavy-traffic road pavements in my country, and has been used more and more in road construction. attention. With the rapid development of our country's economy, the traffic volume of roads has increased sharply and the axle load of automobiles has become increasingly heavy, as well as reasons such as design, construction and maintenance. Although many existing cement concrete pavements have not reached the design period, they have appeared to varying degrees. Various diseases and performance degradation have seriously affected the normal use of roads and d...
