Abstract

Experiments to characterize the effects of moisture content and temperature on the mechanical properties of concrete were conducted. Based on these experiments, a new overall material model capable of predicting the mechanical behaviour of concrete subject to elevated temperatures up to 100 °C was developed. The material model estimates the time, temperature and moisture dependency of the compressive and tensile strength, creep and shrinkage of concrete.

Abstract

While the present state of knowledge on the time dependent deformation behaviour of normal and high-strength concrete may be considered as sufficiently determined, the creep and shrinkage of lightweight aggregate (LWA) concrete, particularly of high-strength LWA concrete, can only be specified inadequately. On the basis of the experimental results a prediction model for shrinkage and creep of structural lightweight aggregate concrete was developed.
