Standard Classification of Fireclay and High-Alumina Plastic Refractories and Ramming Mixes
The following bibliographic material is provided to assist you with your purchasing decision:
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.
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.
