Development of Grouting Material for Rehabilitations of Pipeline Using Flyash-Surfactant Cement Mixture Material

Abstract

In recent years, many trenchless rehabilitations of pipeline that are considered of residents' living environment and mitigated the influence on traffic have been developed. Although the grouting material is required to make the established pipe and the lining material unify, it has high mobility etc. The grouting material using the material that was mixed the surface-active agent with the flyash was developed. Usage of flyash instead of cement leads to improving mobility, reducing construction cost and so on.
In this paper, in order to examine the effect on ambient surroundings of the mixture material developed as grouting material, a fundamental investigation is performed and various these results are discussed.
