    A X-RAY STUDY OF JAPANESE PORTLAND-CEMENT CLINKERS. I.

    By Seiji Kondo & Toshiyoshi Yamauchi.

    Abstract

    X-ray analyses ware made of 12 different clinkers manufactured by 9 Japanese portland

    cement plants. Of these clinkers 6 were made by dry process and 6 by wet. The results can

    be abridged as follows:

    (1) All clinkers showed almost same structure although some differences in the amounts of

    constituent minerals and in the degree of their crystal development were observable.

    (2) The chief constituent of these clinkers was similar to the tricalcium silicate reported in "The Study of Calcium Silicates" (S. Kondo & T. Yamauchi, Jour. Jap. Ceram. Assoc., 1934,

    Vol. 42, 479). Also some dicalcium silicate was found. No other constituents could be distinctly

    detected.

    (3) The authors' results agree well with those reported by A. Guttmann & F. Gille of centri

    fuged Alite portions and also those obtained by K. Koyanagi of Alite portioni of a particular

    clinker whose chemical composition was very near to that of Alite.

    (4) Strictly speaking, there were some slight differences between the wet process and dry

    process clinkers.

    Chemical and mineralogical compositions, diffraction paiterns, and interplaner distances are

    given.
