Effect of Chemical Additives on Sloping of Concrete

摘要

Concrete sliding is physical characteristic of concrete. Sliding is observed during the long-term loading conditions. In particular, sliding is the increase of deformations in concrete under the constant loading conditions. By its nature, slope deformations are conducive, although they can cause tension relaxation in the structures. Because of it the tensions are significantly reduced, which may be considered a positive issue in some cases, but relaxation may also have negative effect on pre-tensioned structures. In particular, it can occur unwanted losses of the values of pre-stretched reinforcement. The following factors are mainly influenced on slope capacities: fillers; ratio of water in concrete, age of concrete, environment relative humidity.
