Experience of Application of High Durability Concrete for Transportation Structures in Severe Conditions of the Far North

Abstract

The article presents the experience of using concrete of increased durability for transport structures in the harsh conditions of the North. The main factors determining the durability of concrete are considered, first of all, the quality of local materials for concrete preparation and methods for producing concrete on its basis for arranging road and airfield pavements both from monolithic and prefabricated reinforced concrete slabs of PDN and PAG grades. The results of laboratory studies of PFM-NLK effect complex modifier, specially designed for use in the Far North on the properties of concrete mixture and concrete, which determine its durability are analyzed. The results of testing preparation of concrete at various industrial enterprises, with introduction of products production and production of monolithic coatings at various objects of transport construction are presented. The possibility of developed technologies spreading for production of increased durability concretes in the Far North regions, including during development of the Arctic regions of Russia and the Republic (Sakha), due to the difficult conditions of the region’s harsh climatic and freezing and soil conditions, and economic and environmental conditions is shown
