Hydration of cement composites containing large amount of waste materials
Barbara Pacewska , Iwona Wilińska
AbstractReducing the consumption of cement with simultaneous utilizing waste materials is preferred for reasons of environmental protection. Typical content of materials substituting cement in cement concrete composition does not exceed 35% of mass of binder. More and more interest is aroused to the increase amount of cement supplements above 50%. The mechanism of hydration processes in such complex systems is not fully understood. The aim of this work is to discuss possibilities of using binders with high amount of cement replacements, with particular regard to physical and chemical processes occurring in such systems after addition of water. Based on literature reports and our own research works possibilities of activation of binders containing high amount of cement replacement (e.g. fly ash) were discussed. Further investigations concerning studies on mechanism of physical and chemical processes occurring in such mixtures are needed.
