Freezing Mechanisms of the Concrete in an Area of Variable Water Level of Port Facilities

Abstract The article deals with the problem of concrete durability in area variable water level port facilities. Particular attention was paid to exposure both negative temperatures and sea water. reasons for destruction first winter season under prolonged freezing structures ice were analyzed. authors come conclusion that alternating thawing is not always a major critical value severity frost on an level. Based study mechanism freezing, they concluded course classical approach ensuring by increasing resistance use air-entraining agents does solve one important practical problems – provision period. believe technology requirements should factor structure. They proposed technological methods make it possible reduce sensitivity massive structures.
