Influence of the Nanostructured-Carbon-Based Plasticizing Admixture in a Self-Compacting Concrete Mix on Its Technological Properties.

A study has been made of the influence of adding a nanostructured-carbon-based plasticizing admixture to a self-compacting concrete mix on the properties of heavy-weight structural concrete produced from it. It has been shown that this admixture in the concrete mix changes its structure and makes it possible to produce concrete with exceptional physicomechanical properties. Furthermore, the plasticizing admixture added to a concrete mix ensures the high degree of preservation of its placeability to provide a possibility of transporting this mix for a long period and of using it in monolithic construction. The indicated admixture in the concrete mix reduces its water–cement ratio to 0.2 and ensures good placeability of the mix, which guarantees the high rate of its hardening and considerable improvement in the strength of concrete based on this mix.
