Author(s):

Gilbert L. Butler

Publication:

Symposium Papers

Volume:

Abstract:

Research into methods by which temperature changes could be applied to structural models of concrete structures led to the use of a commerically manufactured solid state heat pump commonly known as a thermoelectric module.

Abstract:

This work was undertaken as part of a study to investigate the effects of sustained elevated temperatures on portland cement concrete as related to its use in a prestressed-concrete-pressure-vessel-reactor.

Abstract:

Mortar and plain concrete beams were subjected to mechanical load cycles in bending and various types of thermal cycles in the range 20 C to 400 C. From measurements of longitudial length changes, beam deflections, and load holding capacity of the beams, comparisions are made between mortar and concrete for thermal expansion, modulus of elasticity, creep deflections, and ultimate load for three types of thermal cycles.
