Acid Rain Erosion Resistance of Concretes Containing Super-Fine Mineral Admixtures

Abstract:

The sulphuric acid erosion resistance of high strength concretes containing limestone powder,titanium slag and silica ash were studied by accelerating cycle sulphuric acid soak tests. It indicates that the introduction of super-fine mineral powders into concrete can improve its sulphuric acid erosion resistance. With fixed 10% limestone powder, blending 10% titanium slag or 15% silica ash can remarkably enhance sulphuric acid erosion resistance of concrete. The concretes containing mineral admixtures such as limestone powder, titanium slag and silica ash can be used in acid rain abundant area.
