Stress Relaxation of Concrete Under Autogenous Early-Age Restrained Shrinkage

This paper presented results that indicated that the stress due to early age restrained autogenous shrinkage varies quite a lot, partly because of the variation in the relaxation capacity of the mixtures. Both the relaxation ratio, defined as the stress generated divided by the theoretical stress, and the relative relaxation, defined as the absolute value of stress relaxation divided by the average applied stress, can be used to illustrate and analyze the variation of the relaxation phenomena as a function of the type of mixture testes.
