Progresses on the Nano Scale Structure Model of C-S-H and the Shrinkage Mechanism
Abstract: As the main component of harden cement paste, the modeling study on the nano scale microstructure of C-S-H is one of the key approach to the composite design and performance prediction of cement based materials. In this paper some classical abstract model of C-S-H and the model based on the electronic microscopy morphology are introduced, the interaction of C-S-H and water is described to interpret the mechanism of the shrinkage of cement based materials. The development of the models of Jennings school and the characters of those models, the interpretation of the shrinkage mechanism of cement with those models and mathematics-physics models of shrinkage are also reviewed. A UIUC model base on the nano morphology of C-S-H is introduced. A good nano scale model of C-S-H must be corres-pond to the morphology of C-S-H, so to find the comprehensive and intrinsical characters of C-S-H morphology and build a model that can interpret the macroscopical performances is very significant to study the shrinkage and cracking of cement based materials.
