SP25-13

Date: 

January 1, 1971

Author(s):

Gilbert L. Butler

Publication:

Symposium Papers

Volume:

25

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:

The present paper describes the results of creep tests carried out at LNEC on two kinds of mass cured concrete; the constant load being applied at different ages (3 to 365 days) and at two test temperatures: room temperature and 45 C.

Abstract:

The dynamic modulus of the concrete and the coefficent of expansion of concrete and reinforced concrete slabs have been determined in the tests reported.

Symposium Papers

Volume:

Abstract:

Measurements taken at four different road section locations show that if there is a temperature differential between the top and bottom of a concrete pavement slab there is a tendency for the slab to curl. When this curling tendency is restrained, as by the weight of the slab itself, large stresses can be created.
