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.
