Author(s):

Antonio Ferreira Da Silveria and Carlos Alberto Florentino

Publication:

Symposium Papers

Volume:

25

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:

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.

Volume:

Abstract:

The effect of temperature on strength of Portland cements was investigated in series of tests made on concretes cast and cured 24 hr in open molds, in still air at 40 C (104 F) and 45 percent R.H. and mortars cast and cured 24 hr in closed molds at temperatures ranging from 15 C (59 F) to 45 C (113 F).
