Using Limestone Aggregates and Different Cements for Enhancing Resistance of Concrete to Sulphuric Acid Attack

The paper reports on a research program that used limestone aggregates together with a binary or ternary cement to investigate the acid resistance of the concretes. Six concretes were investigate including two reference concretes using siliceous aggregates and four concretes using limestone aggregates. The concrete samples were immersed in 1% sulphuric acid solution for over 168 days with the samples being regularly investigated by visual inspection of surface deterioration, , measuring mass change and testing load bearing capacity in compression. The samples were examined after the 168 immersion with scanning electronic microscope for features of paste aggregate interfacial zones and analyzed with energy dispersive X-ray micro-analyzer for evidence of reaction products of acid attack. The results of the research demonstrate that the concrete using limestone aggregates and the ternary cement containing silica fume performed the best.
