ACTION OF SULPHURIC ACID ON CONCRETE. Concrete for leaching tanks in the copper industry, or in any industry where sulphuric acid is used, will always be an unfavourable consideration. Sulphuric acid, attacking the component parts of the cement used in the concrete, breaks them down into sulphates, this action causing the concrete to soften, and go to pieces within a year.
The assumption of Mr. Godfrey that the analysis of shear and the methods of shear reinforcement in concrete beams is one of the most illogical things in all the literature on the subject cannot well be controverted. C.A.P. Turner
Egyptian Period. Trade Guilds, technical institutions, professional associations, and learned societies appear to have existed in some form or other through all the changing periods of recorded history. E. Fiander Etchells
