1st International Conference on Microstructure Related Durability of Cementitious Composites, Nanjing, Çin, 13 - 15 Ekim 2008, cilt.61, ss.233-241
In this study, hydration development of cement mortars has been investigated to simulate the development of hydration products formation at early ages. Cement mortars were prepared by adding naphthalene sulphonate based (NSB) admixture having a retardation effects on cement hydration by different ratios. Microstructural investigation has been made on each cement mortar to characterize the microstructural development of hydration process. Micrographs have been taken under scanning electron microscope (SEM) at early ages such as 1, 2 and 7 days in which naphthalene sulphonate based admixture has the retardation effect more effectively.
