摘要：

The effect of different new sol-gel BaO-TiO2-SiO2 and CaO-BaO-TiO2-SiO2 coatings on long-term durability of glass fiber reinforced cement (GRC) was examined. Flexural strength of GRC was measured after curing for 7 to 150 days. Significant improvement was observed for coated GRC in this study and discussed in terms of the hydrate formation at interface. Concerned with the alkali resistance, CaO-BaO-TiO2-SiO2 coating was more effective than BaO-TiO2-SiO2 coating. In special, the 10CaO-10BaO-60TiO(2)-20SiO(2) coating, prepared by sol-gel method, was recommended for the highest flexural strength of GRC and least corrosion at surface of E-glass fiber.
