| 摘 要： | 通过长达3年的标准养护试验及80℃热水加速老化试验,研究了矿物掺合料粉煤灰、硅灰对耐碱玻璃纤维增强普通硅酸盐水泥(GRC)耐久性的影响,并对矿物掺合料改善GRC耐久性的机理作了初步分析探讨。研究结果表明,粉煤灰和硅灰矿物掺合料可明显改善GRC的长期耐久性。

| Abstract: | The influence of mineral admixtures such as the fly ash and silica fume on the durability of glass fibre reinforced ordinary Portland cement (GRC) is studied in this paper. The investigation includes the influence of the fly ash and silica fume on the strength of GRC in the standard curing for 3 years and in the water at 80℃ for accelerated aging. The mechanisms on improving the durability of GRC with fly ash and silica fume are discussed too. It is found that adding the fly ash and silica fume can improve the strength of GRC in the standard curing and its duration remarkably. |
