    Significance and Use

    This practice is used to standardize mixing, mold conditions, placement and curing of refractory concrete specimens to be used for testing and evaluation under other test methods.

    This practice standardizes laboratory conditions for producing refractory concrete specimens to minimize laboratory-to-laboratory variation and does not attempt to duplicate the conditions of field installations.

    This practice can be used for the preparation of specimens used in referee testing.

    1. Scope

    1.1 This practice covers the mixing, casting and curing of monolithic refractory concrete specimens for use in further testing. It does not apply to monolithic castable refractories intended primarily for gunning applications.

    1.2 The values given in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

    1.3 Various specimen sizes are required for specific test methods. Refer to these test methods to determine the size and number of specimens, which will be required from the sample.

    1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
