Operating Conditions and Damage to the Concrete of Port Facilities on the Southern Coast of Sakhalin

Abstract

The article examines the winter operating conditions of the concrete of various port facilities in the area of variable water level on the southern coast of Sakhalin Island. It analyzes the climatic conditions of the south of Sakhalin being under influence of the cold Sea of Okhotsk and the warm Sea of Japan. The peculiarity of the climatic conditions predetermines various factors of the frost exposure on the concrete structures in the area of variable water level. The article describes the specifics of the port construction on Sakhalin and the factors that determine the concrete durability. It presents the results of surveying the structures with different service life. It has been established that under modern conditions of the construction of port facilities, the concrete destruction may be possible after the first winter period of operation. The processes of the concrete freezing in different sections of the area of variable water level as well as the distinctive types of concrete damage are considered.
