Abstract
Additives and admixtures are used in cement and non-cement-based grouts to modify their fluid and set characteristics. The ability to modify all fluid and set characteristics increases the durability, strength and penetrability of grout. Well designed formulations create balanced stable suspension grouts that reduce the cost of any grouting operation through increased grouting effectiveness by minimizing the cohesion and maximizing the penetrability of a grout via proper application of additives and admixtures.
