| dc.description.abstract | Cracking of concrete at early ages, that may affect the structure durability and even its safety, can be simulated by means of models based on the concepts of degree of hydration and equivalent age, which require the characterization of the concrete during the hydration process of cement. This paper presents the results of the characterization tests of self-compacting concrete and its modeling at early ages according to different models available in the literature. The tests included measurements of developments of the degree of hydration, compressive strength, indirect tensile strength, elastic moduli, creep at loads corresponding to 30% of the strength at 2, 3 and 7 days and autogenous shrinkage. It is concluded that both the maturity method and the degree of hydration concept are valid to predict the evolution of material properties during the hardening process of the tested self-compacting concrete. In addition, best fitting models for most properties are highlighted. |
