| 摘 要： | 研究了影响碱-粉煤灰-碱矿渣水泥(AAFSC)的强度的因素．测定了其凝结时间。结果表明：当水玻璃掺量为3％，硅酸盐水泥熟料为5％以及适量减水剂，其28d抗压强度大于50MPa，且凝结时间正常。AAFSC浆体浸泡液的pH值随着水化龄期的生长而降低，SEM照片显示抗碱玻璃纤维在从FSC浆体中所受侵蚀极小。

| Abstract: | The influence factors of Alkali - activated - Fly ash - Slag cement( AAFSC) on strength were investigated and the setting time of AASFC was determined. The results show that with proper dosage of water reducing agent, when dosage of water glass and Portland cement clinker is respectively 3% and 5% , the 28 days compressive strength of AAFSC is more than 50MPa and the setting time of AAFSC is normal. The pH value of AAFSC immersion liquid decreases with hydration ages. The corrosion of alkali resistant glass fibers in AAFSC paste is very little by SEM. |
