The Structural Engineer, Volume 10, Issue 1, 1932
The President, proposing a very hearty vote of thanks to Mr. Creswell for having put the matter so clearly before the members, said he was wondering when structural engineers would have the opportunity to acquire legal knowledge in addition to all the scientific knowledge they must possess; perhaps the matter was one which might be placed before the Institution’s Board of Examiners. Mr W.C.Cocking(Past Member of Council) paid a tribute to Mr. Creswell in respect of his very happy knack of drawing the attention of professional men to various matters, often of very great importance, but which had previously escaped their attention, and said that the paper referred to many matters which professional men did not often consider.
Dr Oscar Faber said the paper hardly lent itself to discussion in the ordinary manner, because it was such an excellent description of modern cement manufacture,and nobody could argue with anything that was said in the paper. That made it more difficult to arouse at any rate a very fierce discussion. The first years of his own college course were spent in a cement works, and he had been interested in cement ever since, and for that reason he had appreciated the paper very much. In referring to the universal practice of adding gypsum to make cement slow setting, the author said this is added to the extent of anywhere between 2 per cent, and 3 per cent., but the British Standard specification required that it should not exceed 2.75 per cent. This obviously meant that there was some objection to gypsum if it were introduced in excessive quantities. The objection to gypsum was that an excess of it made a cement what was known as unsound, and it gave the cement certain properties which were deleterious to a permanent concrete.
We very much regret that the following printers' errors occurred in the December issue of The Structural Engineer :- Page 398- "Stewart & Partridges,Limited" should read "Stewart & Partners, Limited" Page 404- The figure "330 O.D." should read "300 O.D." Page 409-"Chief Surveyor" should read "Chief Quantity Surveyor" Page 42-"Breaking of cracks" should read "Breathing of Cracks".
