Abstract:

Thermal conductivity and thermal expansion coefficients were measured on various concretes according to temperature and the loss of water up to 500 C. The results are set out and discussed in relation to the other properties previously mentioned.

Abstract:

Shrinkage and creep strains, thermal conductivity and also deformation behavior under load are more or less affected by the moisture content of a concrete structure. The following study of moisture migration under a sustained temperature gradient along the axis of 300 mm long and 80 mm diameter concrete cylinders was undertaken on 1968 by CITRA to obtain some information on the possible moisture movement in the 5.50 m thick cylindrical wall of BUGEY I P.C.R.v. (see P. Launay, annales de l'I.T.B.T.P., May 1970). The corresponding tests were prepared and performed by the Centre d'Etudes Scientifiques et Techniques (CEST) of Grenoble under the supervision of tehcnical department of CITRA, and completed in June 1969.

Publication:

Symposium Papers

Volume:

Abstract:

A discussion is presented on the state-of-the-art of finite element analysis particularly as it applies to the analysis of reactor vessels. The matrix displacement method using the special computer language ASKA as well as a more general approach using FORTRAN IV is presented.

SP34-27

Date: 

January 1, 1972

Author(s):

J.C. Marechal

Publication:

Symposium Papers

Volume:

34

Abstract:

Experimental results are given drawn fro the study of properties of concrete from - 160 C to + 500 C; the variations in the modulus of elasticity and the Poisson ratio varying with the change of state and temperature are discussed in relation with the other thermodynamic properties of the material.
