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.
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
