Design and Installation of Concrete Shielding in the Civil Engineering of Nuclear Constructions; ETUDE ET MISE EN PLACE DES BETONS DE PROTECTION DANS LE GENIE CIVIL DES OUVRAGES NUCLEAIRES
Technical information about high density concretes which are very important for radiation biolcgical shielding is presented. The heavy aggregates (barytes, ilmenite, ferrcphosphore, limonite, magnetite and iron punchings) used to make these concretes were investigated from the point of view of prospecting and physical and chemical characteristics. A general survey of shielding concretes was made involving the study of components and mixing and placing methods. A detailed investigation was also made of some high-density concretes: barytes concrete, with incorporation of iron punchings or iron shot, ferrophosphore concrete, ilmenite concrete, and magnetite concrete, more particularly with regard to grading and mix proportions snd testing process. Two practical designs are described. Specifications are given for barytes concretes and for making the proton-synchrotron "Saturne" shielding blocks. (auth)
