Abstract:
The preparation of concrete is an art requiring as much exact knowledge, experience, skill, and painstakingness as the preparation of steel. It is, if anything, a more difficult art, as the latter is carried on under fixed conditions and everything favors the reduction of the process to a science, while the preparation of concrete seldom takes place under conditions twice alike.. In the first place, the materials themselves vary greatly, from place to place, and from time to time, differing in composition of concrete, and their final deposition as concrete, involves a continual readjustment of the modus operandi. To prepare concrete properly, therefore, it becomes very necessary to do two things as further described in the article.
