Presents reccommended methods and procedures for measuring, ixing, transporting, and placing high density concretes which are used principally for radiation shielding in nuclear construction. Also covered are recommendations on cement, high density aggregates, water, and admixtures. Mixture proportioning of high density concrete is discussed. Reccommendations for preplaced aggregate high density concrete are also included, together with suitable grout proportions. Mixing equipment, form construction, placing procedures, and methods of consolidation are described. Quality control, inspection, and testing are emphasized, and a list of references is included.
