Determination of Amount of 'Plastiment a' Retarder in Hardened Concrete
A reliable colorimetric method for determining Plastiment A retarder in hardened concrete containing gravel, limestone, or slag aggregates has been developed which generally yields an absolute accuracy of plus or minus 0.4 oz per sack of cement. Details of the method are given, and development of similar techniques is recommended for other retarders. The study resulted from instances of overdosage of retarder in bridge deck concrete. The analytical method will also detect omission of retarder that would result in early setting of concrete.
