Deterioration of Mortar Composites in Acidic Environment

Abstract:

In recent years, the rapid deterioration of various reinforced concrete structures has been widely recognized as worldwide problem. Acidic environments are very aggressive to concrete structures, as well as promote their degradation. The aim of this experimental study is to make a comparative analysis of the behavior of mortars prepared by cement (CPJ-CEM II/A) and composites of different percentage by weight of polymer. It highlights the influence of PET on the durability of these mortars. After 28 days of curing specimens in water, they are put in acid solutions of the same concentration 3% (HCl, H₂SO₄, H₃PO₄ and HNO₃). Weights tests measuring are made at different ages. The results demonstrate the beneficial effect of the addition of PET in the modified materials against chemical attack by various acids. The formations which appear such as different calcium salts were determined by X-ray diffraction. These results take into account the recycling of plastic waste in the manufacture of modified mortars against aggressive environment.
