SIGNIFICANCE AND USE 3.1 This classification defines a group of classes for use by those producing or purchasing fireclay and high-alumina plastic refractories and ramming mixes. Each class is limited by PCE or alumina content, or both. This classification is frequently used as a specification when the properties shown in Table 1 are the only items specified. (A) NR = not required. SCOPE 1.1 This classification covers fireclay and high-alumina plastic refractories and ramming mixes that can be pounded or rammed into place to form a monolithic structure. The terms “plastic” and “ramming mix” are generally intended to describe the workability of the material. In this regard, plastics are considered to be materials having a workability index of more than 15 % in accordance with Test Method C181, while ramming mixes generally have less than 15 % workability by the same procedure. 1.2 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
Abstract
Overview
ASTM C673-97(2022): Standard Classification of Fireclay and High-Alumina Plastic Refractories and Ramming Mixes is an internationally recognized classification developed by ASTM International. This standard establishes clear classes for fireclay and high-alumina plastic refractories and ramming mixes, focusing on their composition and workability. Widely adopted by manufacturers and purchasers, ASTM C673-97(2022) enables uniform specification and procurement by categorizing materials based on pyrometric cone equivalent (PCE) and alumina content, or both.
These refractories are critical in forming monolithic structures through pounding or ramming, making them essential in high-temperature industrial applications such as furnaces, kilns, and incinerators where robust and reliable lining materials are required.
Key Topics
- Material Scope: Covers both fireclay and high-alumina plastic refractories and ramming mixes, distinguishing between their workability characteristics.
- Plastics: Materials with workability index > 15% (per ASTM C181)
- Ramming mixes: Materials with workability index
