| Abstract | Shrinkage compensating cements currently used in structural grouts do not provide the required volume stability in some in-service environments. Consequently, some grout manufacturers use expansive admixtures. However, erratic results in the application of the expansive admixtures have been reported. Four proprietary expansive admixtures, two lime-based and two calcium sulfoaluminate- (CSA) based, were investigated to determine their suitability as alternatives for Type K cement in structural grout compositions. The results show that at higher dosages, the CSA-based admixtures provide better shrinkage compensation than either Type K cement or lime-based expansive admixtures. The CSA-based admixtures enable structural grouts to meet the requirements of the more demanding in-service environments. |
