概要

論文の詳細を見る
Alumina precursor was coated on the glass fibers by sol-gel method using aluminum alkoxide solution. The addition of silane coupling agent led to high adhesion force between glass fiber and alumina precursor films. Alumina precursor coating on glass fibers enhanced alkali-resistance and tensile strength. GRC was produced using alumina precursor coating glass fiber. Microstructure of fiber reinforced cement was observed by SEMafter the cure in the water at several temperatures. Alumina coating demonstrated that mechanical property of fiber reinforced cement was superior to original GRC after curing in the water at several temperatures.
