Methods of Controlling Grout for Prestressed, Post-Tensioned Structures
A study was made to determine the effects of various admixtures, cement brands, and air entrapment/entrainment on the quality of neat cement grout. The relationship between these parameters and compressive strength was also investigated. A number of laboratory grout mixing experiments were performed. Results are tabulated for comparison, and where applicable, statistical analyses performed. It was found that admixtures, in the quantity used for this study, in all cases, decreased compressive strengths and increased the bleeding of grout. Higher mixing speeds tended to result in slightly more air entrapment. (Author)
