Advanced Building Materials Based on Zeolite-Containing Raw Materials of Yakutia

Abstract

The article presents the results of the research department “Production of building materials, products and structures” NEFU. The main task was the rational use of zeolite-containing raw materials from the Khonguruu deposit (Yakutia) in the production of effective building materials. The specified deposit is the source of the most common clinoptilolite type zeolites with an admixture of heulandite. The studies were carried out according to the priority scheme of the main building materials for the conditions of hard-to-reach regions of the Arctic and the North: binder (Portland cement with a mineral additive) – heat-insulating material (granular foamed zeolite) – lightweight concrete (foamed zeolite concrete) for mobile construction technologies. Thus, the possibility and efficiency of using zeolite in these types of building materials has been substantiated. At the same time, savings of 30–40% of Portland cement clinker, a decrease in material consumption and construction costs can be achieved. The developed materials and technologies based on zeolite-containing raw materials Khonguruu are intended to ensure the construction of buildings and structures on the principle of a full cycle of construction of energy-efficient buildings, taking into account the conditions for locating production in hard-to-reach regions of the Arctic and the North (from the production of building materials to construction).
