In continuing the previous study, the author reports in present paper on the influence of 0.5% fluorspar in the high silica and lime raw mixture of H. M. above 2.15.
The auther burnt the raw mixtures of H. M., as clinker, 2.18, 2.20, 2.24 and 2.31 which are difficult on the usual burning, and got good cements with H. M. up to 2.24 by adding 0.5% fluorspar.
