The President: "It gives me great pleasure to call on Professor Howat to present the paper written jointly with P. R. Jochens and C. W. Wolhuter entitled, 'Utilisation of slags for the manufacture of cement.' After the presentation of the paper the President said: "Thank you, Professor Howat, for so ably introducing the paper prepared by yourself, Dr Jochens and Mr Wolhuter. Once again we are deeply indebted to you for bringing to our attention a new development in the metallurgical field, this time a technique for assessing the suitability of slags for the production of slag cement, and thereby providing a means of turning a waste material into a valuable asset. May we hope that this will lead to an end to unsightly slag dumps and, at the same time, to some conservation of our local limestone resources. Discussion within this Institute on the problems of cement manufacture, has of recent years been all too infrequent, and we thank you for bringing this interesting and important subject again to our notice. We are doubly grateful to you and your co-authors. May I now call on Dr Stutterheim, Deputy Director of the Council for Scientific and Industrial Research, to contribute to your paper, and to tell us something about the Conference on the Chemistry of Cement which he attended in Tokyo towards the end of last year." (Applause.) Dr N. Stutterheim, Mr B. F. van der Merwe and Dr F. S. Fulton then contributed to the paper. (These contributions will appear in a later issue of the Journal.) PAPERS OPEN FOR DISCUSSION The President: "Listed on the agenda are papers open for discussion. I would suggest that anyone wishing to contribute to these papars, submit their contributions to the Secretary in writing." CONCLUSION The President: "I would like to thank everybody for their attendance here tonight, and on your behalf I am sure you would like me to thank the authors and the contributors for the most interesting time that we have had this evening. Thank you very much." The meeting closed at 6.00 p.m. NOTICE SYMPOSIUM ON THE RECOVERY OF PYRITE A symposium on the recovery of pyrite will be held on 12th and 13th June, 1969 at Kelvin House, Johannesburg under the auspices of the Institute and the National Institute for Metallurgy.
