| description | <span>The negative effect of acidic attack on the properties of concrete and cement mortar is a topic <span>of increasing significance in the recent years. Many attempts has occurred to mitigate this negative <span>impact by improving the properties of concrete and increase resistance to acids by using additives. <span>The present study includes treatment of sand by alkaline material and examine the effect of <span>treatment on cement mortar resistance towards hydrochloric and sulfuric acid. Results show that <span>sand treatment by alkaline material significantly enhance mortar ability to resist acids. In terms of <span>loss weight, the maximum weight rate gain was 25.54% for specimens immersed in Hydrochloric <span>acid with water cement ratio 40%. For specimens immersed in HCl, the average gain in <span>compressive strength is (20.15-19.433)% for w/c (40-45)% respectively. The average gain in <span>modulus of rupture toward the influence of H<span>2<span>SO<span>4 <span>is (18.37–17.99)% for w/c (40-45)%, respectively.</span></span></span></span></span></span></span></span></span></span></span></span></span></span> |
