This specification covers fluidifier for grout used for preplaced-aggregate (PA) concrete. Grout ingredients shall conform to the specified requirements for Portland cement, pozzolan, and fine aggregate composition. The fluidifier, tested in grout shall conform to the specified values of reduction in mixing water, expansion, bleeding, increase in water retentivity, initial and final setting time, and compressive strength.
