Abstract:
Observations from tests show that reductions in strength, and changes in physical properties, that occur in portland cement concrete as a result of cyclic heat to 600 F (316 C), can be accurately evaluated and accomodated into a fesible design for a concrete structure. The preliminary test results, developed for the concrete used in the support for a reactor vessel, show the significance in the cement factor for achieving the least amount of deterioration due to high temperature cycling, with special reference to heat resistant corse aggregate mixes.
