PROPERTIES OF EARLY AGE CONCRETE - EXPERIMENTS AND MODELLING

摘要

For the simulation of temperature fields and restraint stresses in hardening concrete structures, the properties of early age concrete has to be known. This report is an extract of a research project which dealt with the thermal and mechanical properties, stress-strain curve, creep and relaxation and autogenous shrinkage of early age concrete. Here, only the mechanical short and long-term properties of early age concrete will be dealt with. In addition to the experimental results, models will be presented.
