Problems of Energy Efficiency When Design of Construction Objects for Transport Infrastructure
Abstract The main task of this work is focused on providing of energy efficiency by correction of requirements to heat- and sound-insulation of autoclave cellular concrete and development of special purpose materials. The high-effective technological solution is proposed. It is based on application of high-reactive aluminosilicate components in cellular concrete to improve porous structure. Using a scanning electron microscopy (SEM), gas adsorption method (BET) the analysis of cellular material microstructure at macro- and micro-level is accomplished; criteria of optimal porosity formation taking into account amount, size and shape of pores as well as density of interpore partition are determined. According to refined parameters and experimental data the relationship between the concrete structure and its resistance to sorption capacity and vapor permeability when surround humidity variation in range of 80–97% are determined. Also reducing of heat-conductivity coefficient for the concrete is observed. It allows construction of stored buildings such as garages as well as light maintenance of vehicle without additional winterization. Generally, on the base of the data obtained in this work the developed autoclave cellular concrete is energy-effective and rational material when design, modernization and service of construction objects of transport infrastructure.
