Análise do comportamento reológico de suspensões com micro-aglomerante para emprego em injeções através de resultados de ensaios de laboratório.

Abstract

The present work treats of the experimental determination of the reology’s characteristics of suspensions with micro-cement for injection in soils or rocks, considering that, it is an important factor for the success of an injection operation. The material used in the tests is Dyckerhoff-Sohl-Feinst-Bindemittel-F, being observed, as the reology’s characteristics are altered, in elapsing of the time, for other factors, as variations in the execution of the mixture. The study material was developed as alternative for use in reinforcements and impermeabilization of soils, through injection in grain sizes among medium and fine sand, with the advantage of not having harmful influence in the characteristics of the underground water. The material can be used in fissures or fractures in rocks and fissures in concrete pieces.
