内容简介

CaO is a superior basic material that has numerous advantages, including a high melting point (2572 deg C), a structure that is very stable thermodynamically, and calcium carbonate, which can be used as the raw material for making high purity calcia aggregate, is available with a large quantity of reserves in Japan. MgO is also a superior basic material, which is easy to obtain in large quantity from sea water, and the reserves are essentially unlimited. However because both CaO and MgO readily react with moisture and water, it is necessary to exercise great care in using them in refractories, because of the humidity in the atmosphere and possible water exposure, thus the applications are extremely limited. Consequently, for the main purpose of this work to improve the hydration resistance of CaO-MgO aggregate, the effect of sodium silicate on the hydration resistance was investigated. The results of the investigation are summarized in this paper.
