Durability of Fine-Grained High-Strength Concrete in Corrosive Environment

Abstract

Abstract The use of fine-grained high-strength concrete of man-made materials as components entails the risk of corrosion processes in concrete. A peculiarity of possible corrosion processes is iron-containing sulfosilicating compounds in rubble, which greatly complicates the prediction of structure durability made of such concrete. High-strength construction composites, which differ from ordinary concrete with a higher content of cement stone, fine particles of binder and fillers, as well as a multi-component composition, necessitate the development and modification of ways to increase and predict structure durability made of such materials. The paper deals with design and technology of product manufacturing from fine-grained high-strength concrete of increased durability in close connection with the assessment of their reliability and durability.
