Hydration of cement systems in the presence of novel LDH nanocomposites

Development of a new composite technology for programmed delivery and control of admixture effects in concrete and other cement-based materials present is described. A series of new organo-mineral phases have been developed by a "chimie douce" technique and analyzed using a combination of analytical techniques: X-ray diffraction (XRD), infrared spectroscopy (IR), and scanning electron microscopy (SEM). Conduction calorimetry was utilized to …
