Operation of Building Envelopes in Humid and Wet Environment in the North of Krasnoyarsk Krai

Abstract

The paper dwells upon the relevance of comprehensive analysis into the durability and frost resistance of stone envelopes for industrial buildings operating in extreme cold. The inner environment of a facility and the climate directly affect the lifespan of the industrial building in the North of Krasnoyarsk Krai. The paper analyzes the primary causes and consequences of frost deterioration of building envelopes operated in humid or wet environment. It presents the attributes that indicate the condition of outer building walls of varying age; such attributes point to the deviation from the normal condition. The condition of supports was categorized by examination. The paper further summarizes the results of processing the obtained data on the temperature and humidity the buildings and their envelopes are operated at. It presents the results of testing the efficiency of brick, fly-ash autoclaved aerated concrete, and ceramsite concrete as envelope materials.
