Abstract:
The purpose of this continuing investigation is to develop information regarding the time-dependent deformation behavior of concrete in the presence of varying temperature, moisture, and loading conditions similar to those encountered in a prestressed concrete reactor vessel (PCRV). This particular investigation is concerned with one concrete strength, three aggregate types, one cement, two moisture conditions, two testing temperature, and four loading conditions.

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.

A report on the first phase of a program of investigation of the mechanical properties of concrete subject to high temperatures is presented. The first phase had two objectives: 1) to evaluate instrumentation and techniques and 2) to study the effect of temperature on the mechanical characteristics of concrete under uniaxial stress.

An investigation of creep Poisson's ratio under continuous load is presented. The objective of the investigation was to study the creep behavior of concrete subjected to multiaxial state of stress and elevated temperatures.

Shrinkage and creep under different stresses were studied on several specimens of concrete. Once analyzed and discussed, the experimental results reveal to two classes of distinct phenomena: at high temperatures, the concrete, freed of its evaporable water, would appear to behave according to the classical Arrhenius equation during changes in state; for lower temperatures, pure creep due to temperature would be very slight, shrinkage and shrinkage under loading would vary with the steam pressures bringng about the desorption of evaporable water.
