Acid Resistance Bricks are specialized chemical-resistant masonry units used in industrial environments where floors, walls, tanks, trenches and process areas may come into contact with acidic substances. These bricks are selected to provide a protective masonry lining in suitable chemical-service applications.
Acid-resistant masonry units are classified under ASTM C279 according to their absorption and acid-resistance requirements:
These are standard classifications, not confirmation of the grades currently manufactured by Oryvia. Please contact our team to confirm available product grades and applicable technical documentation.
Acid-resistant bricks are used in suitable industrial construction and lining applications where chemical protection is required. Potential applications include:
Actual suitability must be checked against the chemical composition, concentration, temperature and operating conditions. Acid-resistant bricks should not be assumed suitable for hydrofluoric acid, perchloric acid or every other aggressive chemical.
