Abstract

Development and application of highly effective complex chemical additives in road concrete, which have properties of anticorrosive and waterproof nature, and at the same time keeps high mechanical strength when used as a roadbed. In this regard, this paper presents experimental results on the study of the nature of water resistance, frost resistance and anti-corrosion properties under operating conditions in a natural aggressive environment. There is a huge reserve of basalt deposit in our republic, which is not yet used on a large scale. In this article the ways of using basalt-complex chemical additive as increasing corrosion resistance of road concrete are given.

In this case, not only is there a saving in energy consumption, but also this technology does not require large financial investments. Below are the test results of some hardening accelerator modifiers with BCHD additives of conventional heavy concretes for road construction.
