Energy Efficient Polystyrene Aerated Concrete Composite Products and Condition Monitoring for Building Structures and Facilities in the Arctic Regions

Abstract

The harsh climatic conditions of the Arctic zone of the Russian Federation in combination with the current requirements for ensuring comfortable accommodation conditions in buildings and structures lead to strengthening of respective thermal protection regulations. The article outlines the basics for the multi-layer composite material technology based on the use of aerated concrete and polystyrene foam. The novelty of the technology, as confirmed by respective patents of the Russian Federation, consists in layering of aerated concrete and non-foamed or partially foamed polystyrene into a mold, followed by its closing with a lid and subsequent heat and moisture treatment by steaming. The steaming process triggers spontaneous expansion of the aerated concrete mixture and polystyrene, compaction of their structural layers, and acceleration of concrete curing. The result is a composite product with improved performance, complying with the current regulatory requirements for the thermal protection of buildings. In order to ensure the reliability and durability of construction projects, systematic quality control is required for all raw materials used in manufacturing of building structures, as well as proper condition monitoring for all operated buildings and structures. The Kola Testing Centre for Building Materials and Articles (KTCBMA), established 20 years ago, conducts certification and definitive testing of building materials for compliance with the current standards, as well as non-destructive testing of concrete and reinforced concrete structures.
