The research problem which was chosen is closely connected with a question which is of wide-spread importance to the prairie provinces of Canada, and to the corresponding states lying south of the international boundary, the question of the so-called "Actions of Alkali on Concrete". It has been proved beyond doubt that those regions of the Western plains having a poor rainfall coupled with bad drainage have extraordinary amounts of soluble salts present in the soil. The difficulties which engineers have encountered in the dry belt of Western Canada and the Western states have, in some cases, proved well-nigh insurmountable, and have resulted in bringing this problem before both scientists and the public, in a very striking manner. Alternately titled The action of sulphate solutions on Portland cement.
