Abstract　Highly-activative flyash is a new kind of specially processing grouting material whose main component is the flyash, an industrial waste material. Using the highly-activative flyash with other additives which can strengthen cementation, increase early strength and improve grout performance can meet the requirements of grouting work. Compared with common silicate cement, the material possesses of the features of well flowability, proper cement time, high compression strength and high ratio of cemented rock in grouting application. Good results have got in static pressure grouting and high pressure jet grouting engineering.
