When mortar or concrete reacts to sulfuric acid, dihydrated gypsum film is formed around the particulate of the fine aggregate. This dihydrated gypsum filmFEATURE Gypsum The role of gypsum in cement,India’s cement production capacity stood at around 502 million tonnes per year (mtpa) in 2018 and is expected to reach 550 mtpa by 2025. Typically, manufacturing cement uses 2 to 4 per cent gypsum per tonne of cement. Thus the country requires importing substantial gypsum to cater to the requirements of cement industry. This has made the
Sulfuric Acid Storage Guide - Aetna Plastics
• Sulfuric acid can create a highly flammable hydrogen gas if it is spilled on metals. • Skin and other bodily burns from sulfuric acid can be more serious than burns from other strong acids. Sulfuric acid dehydrates whatever it touches, and the heat caused by that reaction with water can create secondary thermal damage.Acid Resistance - Portland Cement Association,Portland cement concrete usually does not have good resistance to acids. Some weak acids, however, can be tolerated, particularly if the exposure is occasional ().There are essentially three ways to improve concrete’s resistance to acids, (1) choosing the right concrete composition to make it as impermeable as possible, (2) isolating it from the environment by using a suitableAcid Attack - Mechanism,Acid X + CH CX + H. Acid + Calcium Hydroxide Calcium Salt + Water. More aggressive acids such as hydrochloric, acetic, nitric, and sulfuric acids produce calcium salts that are very soluble. Less aggressive acids such as phosphoric and humic acids produce calcium salts with a lower solubility.,,,
