    Based on the knowledge of the deterioration mechanisms of different acid solutions the performance of UHPC – amongst others – in different acid environments was comparatively tested. The interconnection between the acid solutions and UHPC was examined by pH-value measurements, light microscopy (LM), scanning electron microscopy with energy dispersive X-ray analyzer (SEM + EDX), X-ray diffraction (XRD) and thermal analysis (DTA/TG). To achieve a consistent accelerated and reproducible ageing the acid solution has to be constantly homogenized, the pH-value and the saturation of the solution has to be controlled as well as adjusted. The results show that concretes with very high strength (such as UHPC) have not automatically an excellent resistance against acid solutions. A very high acid resistance can only be achieved by a very low capillary porosity and a very low reactivity against the acid solution.
