First concretes for Mochovce nuclear power plant

The possibility was studied of using local sources of aggregates for concrete mixes for the construction of the Mochovce nuclear power plant. The results of the surveys of several localities are presented. Tests were made of 3rd class concretes with the appropriate consistence for concrete mixes designed for the foundation plate. The tests were to prove the appropriateness of the use of fine dolomite aggregates from local sources. The results of the tests have as yet not been evaluated but the statistical assessment showed that the concretes met all criteria. The flow chart is given of concreting and of concrete strength and temperature control. (J.P.)
