A Study on CaO-SiO2-H2O System Hydrates Produced by Hydrothermal Reaction under High Pressure

[摘要] It is a fundamental study for the hardened bodies of CaO-SiO2-H2O system to clear up various physical properties and structures of the products, using the Seosan quartz and Ca(OH)2(C. P. grade) as raw materials. Various samples were obtained by varying CaO/SiO2 mole ratio (0.3¡­2.1) and hydrothermal conditions (100¡­220¡É and 2¡­14hr.) within the given limit. It was found that tobermorite phase as hydrate is contained in the hardened bodies and that the development of crystal has a great influence on the strengths and other physical properties of hardened bodies.
