Additives and Admixtures in Cement Based Grouts
Additives and admixtures are used in cement and non-cement-based grouts to modify their fluid and set characteristics.
An Alternate Compaction Grouting Technique
This paper describes an alternate compaction grouting system. It also provides the theory and a mathematical model to assess and quantify the degree of soil improvement caused by compaction grouting.
Hot Bitumen Grouting: The antidote for catastrophic inflows
Hot bitumen grouting technology has continually evolved since its early applications almost a century ago in France, Germany and the USA to seal persistent leaks in tunnels…
Contemporary Issues in Rock Grouting and Formulation of Engineered Cement Based Suspension Grouts
When utilizing a cement based suspension grout, it is important to use balanced stable grout formulations with the proper rheology for optimum penetrability and desired set characteristics.
Hot Bitumen Grouting – Rediscovered (Heiβbitumenverpressung – wiederentdeckt)
Hot bitumen grouting technology has continually evolved since its early applications almost a century ago in the USA, in France and Germany, to seal persistent leaks in and below dams, in tunnels and for erosion protection along canals.
