The Structural Engineer, Volume 5, Issue 5, 1927
There are many old ideas which have been exploded in recent years, and one of them is that it is necessary to aerate cement to make it slow setting; the usual method used to be to lay the cement out on a dry floor for a month or so. This is quite unnecessary with modern cements, as the time of setting is arranged during the manufacture, and the sooner the cement is used after delivery has been made, the better. Professor Duff Abrams made a series of experiments over 4 1/2 years, showing the effect of storage of cement under various conditions. Cement stored in a shed in the laboratory yard, gave an average strength ratio for the ages at which the tests were made:- G. McLean Gibson

It has been interesting and instructing to read in recent issues of The Structural Engineer, papers and the discussions thereon, in which references were made to the qualities from an anti-corrosive point of view of the numerous types of paints in use at the present time. H. Pontet
