Concrete corrosion caused by sulfuric acid attack is a known phenomenon in sewer systems, resulting in significant economic losses and environmental problems. However, there is a scarcity of reported laboratory simulations and experimental work investigating the contributing factors controlling the corrosion. In this investigation, funded by the U.K.’s Engineering and Physical Sciences Research Council (EPSRC), the effect of temperature and the acidity of sulfuric acid solution on concrete specimens extracted from brand-new concrete sewers has been investigated. In this investigation, the concrete samples are submerged in three sulfuric acid solutions (, 1, and 2) for 91 days under different temperatures (10, 20, and 30°C). Mass loss and compressive strength of the concrete specimens were tested and recorded at 7, 14, 28, 42, 56, and 91 days, providing interesting data for visualizing the changes taking place …
