Technical and Economical Efficiency for Application of Nanomodified High-Strength Lightweight Concretes

Abstract:

Article Preview

The development of construction technologies is impossible without the proper estimation of economical efficiency. Some results of technical and economical efficiency of the developed high-strength structural lightweight concretes are presented in the article. Overview concerning world practice of research and application of lightweight concrete composition are made. The main properties and advantages of developed energy efficient high-strength lightweight concretes are described. The method of calculation of economic efficiency of concrete by means of reduction of total construction weight and increasing of floors’ number is proposed. Dependence between efficiency, footprint of building and number of floors is presented. It is shown that economical calculation for developed material which is based only on the cost of the material itself does not allow to obtain adequate data concerning prospect and competitiveness of the material. The authors offer method of calculating the economic efficiency of the developed high-strength lightweight concrete which takes into account the technical properties of the new material. The results of the study showed that the application of high-strength lightweight concrete is more effective than traditional kinds of the concretes.
