Peculiarities of structure formation processes in nonautoclaved aerated concrete produced using industrial wastes

Abstract

Following the strategy of sustainable development and the principle of applying the best available technologies, energy saving in Ukrainian Housing and Public Utilities Sector is achieved by constructing energy efficient buildings due to applying efficient building materials. Development of modern building technologies in all technologically advanced countries is aimed at developing cost-effective, efficient materials the use of which can reduce energy costs and consumption of raw materials. Aerated concrete is the optimal material for housing because it has wide density and durability range, the properties being important for solving various structural problems. The aerated concrete based on the modified cementitious system containing an additional cementitious material, that of carbonate-bearing salt waste is characterized by the compressive strength of 2.7 MPa with the density of 650 kg/m3 after 28 days of hardening.
