Control of fluid properties of particulate grouts: Part 1 - General concepts

Historically, the challenges posed to particulate (i.e., cement-based) grouting in certain adverse environments in the geotechnical construction field have not been reliably, satisfactorily or economically solved. However, in recent years, extremely significant developments in the understanding of hydration and rheology control have been made, and which now offer extraordinary potential to the practitioner. Equally important advances have been made with grout formulations to resist washout and increase formation penetrability. This paper is the first of two companion papers, and provides general background to these new developments.
