EXPERIMENTAL INVESTIGATION ON RESTRAINED SHRINKAGE TEST OF CONCRETE

摘要

Nowadays, the evaluation of the concrete early age shrinkage is usually on the basic of the free shrinkage test data. But the restrained shrinkage test is more effective on the research of the early cracking. Our group researched and developed a restrained shrinkage test machine. It can realize different degree restraining of the concrete specimen and the automatic data collection.
