Technical paper: A review of some of the properties of Geoseal MQ-5 and silicate-Hardener 600B grouts

Murat Mollamahmutoglu, Civil engineering department, Gazi University, Ankara, Turkey; and GS Littlejohn, Civil engineering department, University of Bradford, UK. This paper was first published in GE’s September 1995 edition.


The purpose of this paper is to provide data on some physicochemical characteristics such as initial viscosity, viscosity-time development, syneresis and gel time for Geoseal MQ-5 and silicate-Hardener 600B chemical grouts. The results of permeation tests are also described with particular reference to groutability of Leighton Buzzard Sand and Thames Ballast Sand using the two chemical grout systems. Unconfined compressive strengths of the grouted sands are provided where permeation has been achieved.
