Prognostication of concrete constructions durability based on experience in building and exploitation of maritime coast-protecting structures on Sakhalin Island

Abstract

The normative foundations in the field of durability ensuring have been considered. Experience in building and exploitation of hydraulic structures in severe hydrometeorological conditions of Sakhalin Island coast has been analyzed. The results of designing of concrete’s durability on the prescriptive base of normative documents are presented. The time period, which can be adopted as estimated lifetime of structures at the designing stage, is proposed. The main reasons of concrete’s degradation, observed in the earliest exploitation periods, have been revealed.
