PROSPECTS FOR THE APPLICATION OF ICE COMPOSITE MATERIALS FOR THE CONSTRUCTION OF ICE CROSSINGS

Ice as a structural material is considered as a pavement material, a substitute for traditional building materials in the northern construction and climatic zone. Improvement in ice strength can be achieved by macro- and micro-reinforcement. In the North and the Arctic conditions, materials of natural origin from local raw materials are economically and technologically effective and environmentally friendly types of reinforcing fillers.
The authors investigate the possibility of using natural fibrous fillers (hay fibers and basalt fiber) in an ice matrix as a reinforcing additive. They demonstrate that the introduction of the used fillers leads to a two-, three-fold increase in the bending strength of fresh ice. Ice composite materials can be used as materials for construction and engineering purposes, as well as a pavement material applied in the Arctic regions.
The authors carry out a predictive assessment of the reduction in the permitted time for the start-up of an ice crossing from such composite materials through northern water bodies and show that the strengthening of the ice crossing by layer-by-layer freezing of a mixture of water and basalt fiber will lead to a significant reduction in the indicated terms.
