Abstract
Time dependence of concrete fracture, in particular the effect of loading rate has been studied mainly in the dynamic range. In the present work, a previous investigation of the rate effect in the static range that covered times to peak from 1 to 300,000 seconds is extended. For this purpose, three-point-bend specimens of three different sizes are subjected to either a sudden 1000-fold increase of the loading rate or a 10-fold sudden decrease of the loading rate. Results obtained including those of a previous study indicate that there exists a significant difference in fracture behaviour for short-time and long-time loads.
