Durability of multicomponent concrete in aggressive environments

The use of technogenic materials as fine grained high strength concrete components entails the risk of corrosion processes in concrete. A feature of possible corrosion processes is the presence of sulfide containing iron compounds in crushed stone, which greatly complicates the prediction of the durability of structures made of such concrete. High strength building composites, which differ from ordinary concrete in the increased content of cement stone, fine particles of binder and fillers, as well as the multicomponent composition, necessitate the development and modification of ways to increase and predict the durability of structures made of such materials. The article deals with the design and manufacturing technology of products from fine grained high strength concrete of increased durability, inextricably linked with the assessment of their reliability and durability.
