Abstract
The main purpose of this research is to minimize the corrosive action of dilute sulfuric acid solution (10% concentration) on concrete industrial water tanks in batteries factories. Concrete incorporated with carbon and polypropylene fiber chips in proportions (3 – 5) % and (0.5 – 1) % by volume was used respectively . Super plasticizer type SP 603 Tufflow with a dosage of (2 -2.6) L/100kg cement was also added . Mechanical test such as compressive strength test and physical tests such as ultrasonic pulse velocity , bulk density, and water absorption tests were done to the samples after curing in normal water for ( 7 , 28 , 60 , 90 , 180 ) days and then they were exposed to dilute sulfuric acid solution (10% concentration) for ( 7 , 30 , 60 , 90, 180) days . The samples cured in water for 28 days , then they were dried in electrical oven at 110°C before they were exposed to acid solution . Test results show a noticeable improvement in durability of suggested concrete mixes against aggressive dilute acids .
