In the reactor building construction at the Rajasthan Atomic Power Project (RAPP) the bulk of material used is concrete. The salient features of manufacture and quality control of concrete are described. The reactor building construction envisages the usage of some 12,000 m/sup 3/ of normal density concrete, some 1000 m/sup 3/ of hesvy density (min 220 lbs/cft) hematite concrete, and some 1000 m/sup 3/ of high strength prestressed concrete 1500 psi). Minimum shrinkage is realized by lowering cement and water contents using a suitable water reducing admixture wherever advisable and controlling temperatures in containment structures --both the heavy concrete containment for the calandria (reactor) vault and the final normal concrete containment forming the building envelope. The specifications and requirements of materials--cement, aggregates, admixtures etc. used for the concrete, the batching and mixing procedure, the criteria for mix design, the special requirements and materials for the manufacture of heavy concrete and low temperature concretes for containment structure and the typical mixes used are described. The parameters and degrees of quality control are discussed. (INIS)
