Abstract | The vast Arctic areas in Russia should be destined not for the rotational-base operation but for peopling and development. The circuit of delivery of construction materials from the inland was and remains seasonal and expensive. Therefore it is necessary to develop local manufacturing of construction materials. Northern territories of the Republic of Sakha (Yakutia) possess considerable sources of mineral stock for production of construction materials. Now Portland cement is one of the widely used hydraulic binders. As a result of the long-term water transport to remote areas of the Republic of Sakha (Yakutia) and the extended storage later on, partial hydration and consolidation of cement takes place. In the meanwhile, many Russian researchers have found that cement with best properties can be produced from old clinker. Portland cement clinker is sintered grains, which conditions its capability for long-term storage without loss of hydraulic properties in severe climatic conditions of the North. Major goal of these studies is production of Portland cement from imported clinker with active mineral additives made of local raw materials. As a result of mechanochemical activation of selected initial components, it is feasible to produce various-purpose high-quality quick-hardening cement (QHC) and dry construction blends (DCB) on a construction site in hard-to-reach areas in the North. The recommended and experimentally evaluated cement mixtures and blends will enable production of construction materials (reinforced concrete, light concrete, foamed concrete, insulations and furnishing materials) from the local minerals, and allows considerable cost-saving of construction owing to great cut-back of energy input and transport costs. |
