Kiewit construction

This observation is important theoretically as well as practically. It has been of late generally maintained that a concrete arch is not an arch at all, but a lintel, without thrust, and that the common form, flat kiewit construction above and arched beneath, is objectionable, as it gives least material at the centre, where a lintel is most strained. The Erfurt experiments directly contradict this view, and kiewit construction it remains for some students kiewit construction of architecture to render the profession a service by repeating them, kiewit construction and, at the kiewit construction same time, actually determining the thrust, for a given load, of kiewit construction arches of particular forms. Until this is done, the concrete construction, which is likely, we may hope, to become before many years the prevailing one in our cities, will be practised with difficulty and uncertainty, if not with danger. Incidentally, a trial was made of the effect of freezing on the concrete. The floor of a room arched in four bays, between iron beams, had just been finished when the weather became cold, and on the morning after its completion the thermometer stood at twenty above zero. The concrete had not been protected in any way, and the contractor was notified that it had been frozen, and must be removed. This was early in December, and it was about the first of April before the work of removal, preliminary to replacing the concrete with new material, was begun. Three bays had been wholly or partly removed when the hardness of the concrete under the workmen's tools kiewit construction attracted attention, and the arch remaining intact was tested with a load of three hundred pounds kiewit construction per square foot, which it bore perfectly.
