Original Abstract

Sand and gravel sealing by chemical injection has been known and used for a long time. Chemical grouting can be expensive. Not even the use of cement sometimes brings the desired effect. Thus, there is an effort to seek new materials and methodologies of grouting. Clay and cement are added in mixtures to limit the use of chemicals. Clay-cement grouts are of better quality and tend to better enter incoherent sediments which require sealing by means of chemical injection. In order to reduce costs, there is an effort to replace traditional clay. Secondary raw materials are a suitable alternative to clay to an extent. One such material is especially fly ash. The paper deals with the suitability of using fly ash and its performance in mixtures. It was found that the use of fly ash brings an improvement of fresh mixture consistency, reduction of w/c ratio and shrinkage. On the other hand, the use of fly ash brought an increase of decantation, permeability, etc. The goal was to design an optimal grouting mixture for additional sealing of embankment dams.
