Capping Compounds are quick-melting sulfur-based materials used in concrete strength testing to ensure even compressive load distribution. Choose from ingot or flake-style compounds that meet ASTM and AASHTO standards for testing cylinders and other concrete specimens.
- Gilson Gray Iron 9000 Capping Compound is a sulfur mortar compound used in concrete strength testing to help ensure even load distribution. Compressive strength is in excess of 8,000psi at two hours. Offers fast set time.
- Vitrobond Ingot Capping Compound is a carbon-filled compound that offers consistent results. Its compressive strength is in excess of 5,000psi at two hours and increases to 7,000psi at seven days. Handles and stores easily.
