    Abstract

    This paper covers the use of water-reducing admixtures in the design and production of ready-mixed concrete. Specification requirements are evaluated against actual on-job problems. Disadvantages in control of uniformity and some advantages that accrue in summertime use are outlined. Producers who use more than one brand of cement are in some difficulty, and data illustrating this fact are presented. Some dangers inherent in reducing cement content are highlighted with test data of on-job sampled specimens.
