Abstract:

The article describes the properties of increased durability of concrete, concrete products, designs. It is noted that the composition of the concrete mix largely determines the permeability of concrete. In this case, the main indicators of the composition of the mixture are: water-cement ratio, cement consumption, the ratio of aggregates and cement, and coarse and fine aggregates. Consideration of problems of improvement of durability should be two aspects: study on the characteristics of the environment and identify the leading factors of the impact of the environment on the reinforcement and concrete, especially for reinforced concrete structures in General, the study of the mechanism and kinetics of corrosion processes and development on this basis of methods of increasing durability of concrete and reinforced concrete in aggressive environments. It is noted that one of the most important properties of concrete affecting its durability is permeability of concrete. Describes ways to improve the water resistance of concrete, reduce its water absorption. The calculated dependences for determination of properties of concrete.

Keywords:

Water resistance, durability of concrete, properties of concrete, reliability.
