Abstract:
From arcurate construction costs taken from the contractor’s records on a cost plus fixed fee contract, it is demonstrated that the use of lightweight, ex-panded shale concrete plus flat-plate design substantially reduced the cost of the structural frame of a two-story office building. Comparative figures are given for eight different types of construction in normal or lightweight concrete. The method of analysis used in designing the lightweight flat plate is discussed. The mix design for the lightweight concrete is given and the plant set-up for the use of mixers in series is described. Results of laboratory tests of control cylinders are shown.
