TEST DEVICE FOR STUDYING THE EARLY-AGE STRESSES AND STRAINS IN CONCRETE. IN: AUTOGENOUS DEFORMATION OF CONCRETE

This paper describes the latest version of a discretized restrained shrinkage (DRS) experimental test equipment and procedure for studying the early-age behavior of hydrating cement-based materials in various thermal conditions. First, results that show the temperature control efficiency and the uniformity of the temperature field within the specimens are provided. Then, the results of tests performed to evaluate both hardware and material effects are presented. A selected series of experiments demonstrate reproducibility of results from the DRS tests. The overall results indicate that the temperature-controlled DRS test can help in the understanding and characterization of early-age behavior of cement-based materials.
