Влияние физико-механических свойств бетона на сопротивление ледовой абразии

Abstract

Concrete is a promising material for construction of offshore ice-resistant structures in the Arctic seas. The reliability and durability of concrete structures are determined by the operating environment and its parameters. One of the most critical parameters is concrete abrasion, which is the least studied phenomenon, that at the same time has a significant impact on the durability of such structures. The authors present a study (experiment and modeling) of concrete properties that affect its resistance to abrasion from the action of ice formations. The course and results of experiments with concrete samples to determine the parameters of their structural properties are presented. The primary characteristics of concretes are ranked according to the tightness of connection with the intensity of ice abrasion. The general model of the intensity of ice abrasion is proposed, nomograms of the dependence of the intensity of ice abrasion on various properties of concrete are presented.
