Low Water Absorption Acid Resistant Brick for Acid-Base Pool Chemical Workshop Flooring Corrosion Protection. Excellent acid & corrosion resistance - withstands inorganic/organic acids, chlorine, HCl, SO2 and acidic salt solutions. High flexural strength >39.2 MPa (up to 54 MPa), resists heavy equipment loads and impacts. Compressive strength >40 MPa, Mohs hardness >7, highly wear-resistant for pedestrian & vehicle traffic. Ultra-low water absorption <0.5%, dense structure prevents liquid penetration and chemical erosion. Superior thermal shock resistance -withstands rapid temperature changes without cracking, ideal for chimneys & reactor linings. Widely used in chemical plants, power plants, smelters, storage tanks, pickling workshops and corrosive flooring & wall linings.
