Concrete is a suitable material for arctic offshore oil and gas drilling and for production platforms. In the splash and tidal zone of these structures concrete is subjected to severe frost-salt attack, chemical attack of sea water, and ice abrasion. In the test series, a method for accelerated testing of arctic freeze-thaw durability in sea water was developed. High-strength air-entrained superplasticized concretes made with blended cement were tested. The test was found to be very severe.
