Abstract

Abstract

Through theoretic analysis, it can be estimated the concrete temperature and contraction stresses for CPR1000 nuclear power plant massive concretepours. However, it is extremely difficult to modelormeasure the strains due to concrete internalself-restraints. This paper present is a practical ethod, which can fully understand the stress state of the concrete through measuring the concrete elastic strains by a specially engineered measuring device. The resulted information is used further to provide abasis forcontrolling cracking in theconcrete.
- control of cracks,
- shrinkage strain,
- thermal strain,
- elastic constraint
