Abstract: Early-age cracking prediction and management are very complex issues which are only partially and still imperfectly explored. This is due to the numerous and often coupled chemical and physical phenomena that are involved in this competition between stress and strength growth. This latter is particularly true for “modern concretes” made of two, three and even more binder types. A six years research program was launched to implement a thorough investigation on this issue in order to develop a calculation code. This paper presents some results of this work and focuses on the effects of sun irradiation on stress distribution in early age concrete structures through trials made on special “THM samples” experimented within CEOS.FR French national project and on peak temperature in concrete walls.
