It is the major objective of this research to promote the development of new markets for pulverized coal burnt ashes in Japan and to advance its use in the existing markets. Many different research projects have been undertaken to accomplish these aims. In the present report it is discussed whether it is possible to utilize pulverized coal burnt ashes, particularly cinder-sand and clinker, to make them marketable. Since the flyash-cement process in manufacturing flyash-based structural materials appears to be a good partial solution of the problem concerning the disposal of pulverized coal burnt ashes, it is considered to be desirable to make further researches for further utility of pulverized coal burnt ashes, particularly cinder-sand and clinker. It is proposed to investigate for this purpose, to begin with, whether pulverized coal burnt ashes is fit to be used as source material for production of mineral wool, and take place among other already established materials for industry. Our inquiries are centered on the following two questions. (1) Assuming certain knowledge concerning the factor to equip substance to be suitable as raw material for mineral wool, whether such knowledge will endorse pulverized coal burnt ashes to be used for the purpose. (2) Assuming that mineral wool can be made from pulverized coal burnt ashes, whether it will be qualified as marketable. As necessary procedure to answer these two questions examination has been conducted of the viscosity of pulverized coal burnt ashes in its melted condition, and question, and qualification of its products ascertained to be marketable as mineral wool. From these researches it is concluded that pulverized coal burnt ashes in Japan can be used as suitable raw material for mineral wool in so far as its physical and chemical properties are concerned.
