On the Texture of Salking-Proof Dolomite Clinker Observed by Electronmicroscope

Abstract

As the burned dolomite has property to slake into powder when exposed to the atomospheric moisture during storage, several attempts to keep out this defect have been taken in industry and discussed scientifically. Previously, some experiments were reported by the author (at the meeting of Ceramic Association of Japan, October, 1950, abstract page 17; June, 1955, abstract of J. Cer. Ass. Japan, 63 [70] 9 296 (1955)) and a new opinion on this question was presented that the burned dolomite clinker might be protected against slaking by having their grain surfaces coated with some reaction products which formed at burning temperature between dolomite and its added substances. This paper deals with an electron-micrographic study to prove the author's view suggested formerly.
