Which ASTM standard is required for abrasion resistance type refractory testing?

The correct answer is ASTM C704. This standard specifically addresses the testing of abrasive resistance for refractories, which is crucial for materials that will experience wear and tear due to mechanical impact or friction in high-temperature environments. ASTM C704 outlines the procedures for determining the abrasion resistance of refractory products, providing a standardized method to assess their durability and effectiveness in service.

Understanding the importance of this testing is essential for selecting the right refractory materials that can withstand the harsh conditions they will face, especially in industrial applications involving high heat. This helps ensure that the materials will maintain their integrity over time, minimizing the need for frequent repairs or replacements.

The other standards mentioned are not focused on abrasion resistance. For example, ASTM C100 deals with the chemical and physical properties of ceramic materials, while ASTM C150 outlines the specifications for portland cement, which is not related to refractory testing. ASTM C200 is related to testing methods for ceramic products, also not specifically geared toward abrasion resistance.
