The Structural Engineer, Volume 39, Issue 12, 1961
THE PRESIDENT introduced the authors, who then presented their paper. Mr. Edwards showed a series of pictures of the B.E.A. Engineering Base at the London Airport, and Mr. Rigg illustrated the method of construction and the general progress of the work.
The paper describes how the basic structure of concrete can be damaged. Concrete hardens by a rystallisation process and is destroyed by chemicals which dissolve the crystals and physical phenomena which disrupt them. P. E. Halstead
THE CHAIRMAN proposed a vote of thanks to the author. Commenting on Mr. Brimer’s apology for having omitted mathematics from the paper, the Chairman said he need not have apologised, for there were some who felt that on occasions such an omission provided the opportunity for members to think more broadly. In any case the Institution was interested in the promotion of the science and art of structural engineering, and perhaps Mr. Brimer had put forward some of the art instead of some of the science. The members were very grateful to him for having contributed the paper, for it had been very interesting to read it and to hear his remarks on what was being done in a country overseas.
