Accumulation of moisture of cellular concrete wall structures in the annual cycle

Abstract

This article delivers the calculation of moisture accumulation of the wall structure in the annual cycle for the climatic conditions of Krasnoyarsk. Analysis is conducted on the multilayer wall structure made of cellular concrete, with the plaster based on cement-sand mortar as top layer and use of thermal insulation in the form of mineral wool board. The subject of this research is the typical corner unit made of cellular concrete in combination with monolithic belt and an inter-floor overlap used in low-rise construction. The author acquires the results of moisture accumulation in layers of the structure for each month within one year, depending on the climatic parameters. The novelty lies in the fact that the outdoor climate and sorption moisture influences the accumulation of moisture in construction materials, creating a large seasonal increase in moisture. Consideration of these factors in the design process, allows making the structures more durable and energy-efficient. The conclusion is made that the distribution of moisture structural layers under climatic conditions. Krasnoyarsk is uneven throughout the year; however, meet the regulations. It is recommended to conducted regulation in the design in order to maintain the level of moisture in construction materials
