ABSTRACT:
This invention relates to the production of vitreous fibrous materials exhibiting excellent resistance to alkaline attack. More particularly, the instant invention is directed to the production of fibers consisting essentially of basalt and zirconia which demonstrate such exceptional resistance to attack from the basic components present in such calcareous cementitious materials as portland cement as to render them especially useful as reinforcing elements in cementitious materials.
