Factors affecting the deterioration of concrete

The behavior of
constructions under actual operating conditions is affected by exposure
to the environment. It is important that concrete roads and airport
pavings are resistant not only to mechanical damage, but also to the
effects of alternate freezing and thawing. The causes of early failure
in concrete have been shown using prefabricated road slabs as an
example. The causes of loss of performance properties of the roadway
have been established, which are primarily dependent on the quality of
raw materials in the concrete. It was found that, aside from
durability, uniformity and porosity are important factors in
determining the frost resistance of concrete roadways. It was shown
that high aluminate content in the cement leads to concrete destruction
in the first year of structure use. The results may also indirectly
indicate a violation of forming technology during slab production.
