Patent number: 11554988Abstract: A method of making a chemical-resistant concrete composition, namely a quartz-based casting composition, is provided. The quartz-based casting composition provides excellent resistance to attack by chemicals, including weak and strong acids. The quartz-based casting composition is useful as concrete in various construction applications where corrosion resistance is needed. The casting composition includes a dry component and a wet component. The dry component includes about 25% to about 100% by weight quartz and the corrosion resistance increases with increasing quartz content.Type: GrantFiled: May 22, 2020Date of Patent: January 17, 2023Assignee: Magneco/Metrel, Inc.Inventors: Michael W. Anderson, Charles W. Connors, Jr.
