Excerpt from the report: ARS research on surface bonding Began in 1967 and is being continued at the College Station, The University of Georgia College of Agriculture Experiment Stations, Athens, Georgia. So far, this technique has been limited to one story construction. Even with one story height, long walls should be cross-braced with partitions or reinforced pilasters as required in conventional block walls. Because of relatively limited testing of the new process (2 ½ years), no guarantee can be made as to the life and durability of the surface bonding. Testing is continuing. Even if some deterioration of the glass fiber should occur due to alkaline reaction of the cement, the walls will continue to be structurally sound if tied down with rods as indicated. USDA is working with industry toward the development of a non-reactive fiber that will assure high durability and life of the bonding mix.
