||Test Method Supports Self-Flowing Castable Refractories
Refractories are nonmetallic materials having those chemical
and physical properties that make them applicable for structures,
or as components of systems, that are exposed to environments
above 1000 degrees F (538 degrees C), as defined in ASTM C 71, Standard Terminology Relating to Refractories.
New from ASTM, C 1446, Standard Test Method for Measuring Consistency and Working Time
of Self-Flowing Castable Refractories will assist those involved
in R&D, quality assurance, construction, and installation of castable
refractories used in steel, non-ferrous, and cement manufacture,
power generation, and heat treatment.
C 1446 applies to self-leveling cast monolithic refractories which
do not require vibration or other energy to flow easily into complex
molds to form an integral structure. It provides a standard method
for characterizing this new type of castable refractory that has
been developed in the last 10 years, says Robert McConnell, applications
and product development manager, Refractories Division, Alcoa
Industrial Chemicals, Bauxite, Ariz.
McConnell led a task group of industry suppliers and manufacturers
of castable refractories who developed the standard under the
jurisdiction of Subcommittee C08.09 on Monolithic Refractories,
in Committee C08 on Refractories.
For further technical information, contact Robert McConnell, Applications and Product Development Manager - Refractories, Alcoa
Industrial Chemicals, Bauxite, AZ 72011. Committee C08 meets October
19 at the Imperial Palace Hotel & Casino, Las Vegas, Nev. (702/731-3311).
