    Abstract

    This specification covers machine made solid uncored carbon brick produced from either metallurgical or petroleum calcined coke, baked, and suitable for use in masonry construction. This material is normally used with carbon filled chemical-resistant mortars. The carbon brick shall exhibit chemical resistance to the following chemical media: nitric acid, hydrofluoric acid, hydrochloric acid, phosphoric acid, sulfuric acid, sodium hydroxide, and potassium hydroxide. It shall also comply with the specified values for compressive strength, modulus of rupture, water absorption, and maximum ash content.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification covers machine made solid uncored carbon brick produced from either metallurgical or petroleum calcined coke, baked to a minimum 1850F (1010C), and suitable for use in masonry construction which will be exposed to various chemicals. These units are designed primarily for industries using hydrofluoric acid, fluoride salts, and high concentrations of alkalies such as sodium and potassium hydroxide. Carbon brick are normally used with carbon filled chemical-resistant mortars.

    TABLE 1 General Guide to Chemical Resistance of Carbon Brick
    Note 1This table is intended for use as a general guide to the resistance of carbon brick in immersion service at ambient temperatures. Specific recommendations should be obtained from the carbon brick manufacturer. Carbon brick can be used to 650F (340C). Over 650F (340C), strict environmental control is paramount to ensure that the environment is non-oxidizing.
