Abstract

Alkali resistant, fiberizable glass compositions are disclosed. These compositions contain TiO2, La203 or CeO2. The glass fibers formed from these compositions are useful in the reinforcement of cementitious materials.

Claims

1. A CEMENTITIOUS PROUCT COMPRISING A COMPOSITE OF REINFORCING MATERIALS AND A CALCIUM SILICATE CEMENTITIOUS MATRIX WHEREIN ONE OF SAID REINFORCING MATERIALS COMPRISES ALKALIRESISTANT, ZIRCONIA FREE GLASS FIBERS, SAID GLASS FIBES CONSISTING ESSNTIALLY OF:

2. The cementitious product of claim 1 wherein said cementitious matrix is Portland cement.

3. The cementitious product of claim 1 wherein said cementitious matrix is concrete.

4. The cementitious product of claim 1 wherein said cementitious matrix is mortar.
