Is it possible to use the d-5 admixture for prestressed reinforced concrete structures?
Yes, it is possible. This is confirmed by the Certificate of Conformity of the D-5 admixture, as well as by the experts’ report of the Concrete and Reinforced Concrete Research Institute titled after A. Gvozdev. Many concrete admixtures contain chemical, aggressive components. Hardening accelerators often contain chlorine. In pre-stressed reinforced concrete structures they cause corrosion of reinforcement. Therefore, that kind of admixtures could be used not everywhere. The D-5 admixture has no restrictions, as it is based on mineral, natural raw materials. Moreover, the D-5 admixture is recommended for use in pre-stressed floor slab manufacturing technology as it prevents corrosion of reinforcement in concrete. As an example we can mention the plant of reinforced concrete structures in Armavir, with which we have been cooperating since 2010. You can see the feedback on our website.
