Abstract


The paper concerns the issue of boron-fluoro-hydrogenous acid (BFH) water solutions influence on concretes, usually used as flooring materials. A considerable destructive effect of this acid is demonstrated, which can be explained by combined influence of high acidity and the action of the hydrogen fluoride. There has been established an inhibiting effect of the super-plasticizer «Mapefluid» upon the destruction speed and hypotheses have been presented as for the mechanism of such effect.
