Efficient Construction Composites for Construction in the North and the Arctic

用于北方和北极地区的高效建筑复合材料

Construction in the North and the Arctic associated with certain features characteristic of the polar territories, with a low level of population density, difficulties in implementing technological methods for the production of building materials and construction, as well as with the requirements for increased protection of construction sites from the harmful effects of the environment. In this regard, the development of effective building composites and methods of protecting structures based on new principles of transdisciplinarity is relevant. The article discusses the problem of improving the technology of new generation composites with increased strength while maintaining high strength indicators to protect against natural environmental influences, as well as the development of a new method for self-healing of concrete structures during operation in the Arctic.

Thus, new methods of obtaining porous composites of increased strength and self-healing of concrete structure using internal and external factors are shown. The essence of the method lies, firstly, in creating a high-density and highstrength structure of the material and, secondly, in the introduction of a reactive mineral, which is part of a fine filler (iron sulfide). This combination provides the appearance of ettringite-like iron-containing calcium hydrates in the thickness of the concrete stone during cracking, which occurs with an increase in the volume of solid and condensed phases.

北方和北极地区的工程建设需考虑极地地区的某些特征，如人口密度低，建筑材料和建造技术实施难度大，以及对建筑场地保护的更高要求，使其免受严苛的自然气候条件影响。在这点上，基于跨学科的新原则开发高效建筑复合材料与结构保护方法是相关的。本文讨论了改进新一代高强复合材料技术的问题，所得材料具有高强度指标以保护结构免受自然环境破坏，此外也开发了一种适用于北极工作环境的自愈合混凝土结构新方法。

进而，给出了使用内部和外部因素获得具有更高强度的多孔复合材料和自愈合混凝土结构新方法。该方法的本质首先在于创造高密度和高强度的材料组织结构，其次在于引入活性矿物，作为细填料（硫化铁）的一部分。这种原料组合在开裂时自混凝土块体内产生类似钙矾石的含铁氢氧化钙，这一过程伴随着固相和凝聚相体积的增加而发生。
