Development of Strength and Deformability of Very Young Concrete
Abstract A description of experiments concerning the development of strength and deformability including fracture mechanics parameters of very young concrete is given. It is shown that the strength of concrete increases during the observed period from 4 hours to 28 days after casting whereas the deformability - e.g. represented by the deflection of notched beams at maximum load - decreases until a minimum is reached and then increases again. The characteristic length lch may be influenced by hydration temperature but not the notch sensitivity; lch reaches a maximum around 8 hours and then decreases continuously up to an age of 28 days.
