Project Objective

Develop corrosion resistant glass fibers compatible with use in reinforcing cements.

Project Abstract

Task 1. Develop new/improved alkali resistant glass compositions for better chemical resistance and better mechanical properties;
Task 2. Test the glasses in different environments; including solutions that model cement pH and ion activity;
Task 3. Characterize glass fibers, especially measure mechanical properties of fibers; behavior of pristine fibers (compared to E-glass or an AR fiber) and then after corrosion treatment;
Task 4. Prepare and characterize fiber-reinforced cement composites.


Anticipated Benefits

Improved, lower cost reinforcement fibers may find wide use in construction.
