Advanced techniques for the study of shrinkage-induced cracking of concrete with recycled aggregates at early age

The present work analyses the impact of the substitution of natural coarse gravel and sand by recycled gravel and sand on the concrete behavior under free and restrained condition since setting. The methodology presented in this paper associates a Temperature Stress Testing Machine (TSTM) with free shrinkage tests and other experimental advanced techniques, such as direct tensile testing and the monitoring of elastic properties using repeated...
