Abstract

It is a fundamental study for the hardened bodies of $CaO-SiO_2-H_2O$ 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 $CaO/SiO_2$ mole ratio (0.3∼2.1) and hydrothermal conditions ($100∼220^{\circ}C$ 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.
