摘要：以攀钢钢渣为主要原料，研究了四种不同细度钢渣粉的主要特性及其对水泥胶砂强度的影响，同时研究了不同掺量钢渣粉和钢渣粉与粉煤灰组成的复合胶凝材料对水泥胶砂强度的影响。结果表明，在钢渣粉掺量为30%时，钢渣粒度越细，比表面积越大，活性指数越高；平均粒径为21.36μm，比表面积为450.8m2/kg的钢渣粉在掺量不大于10%时，28d活性指数可大于100%，但进一步增加掺量后水泥胶砂强度不断降低；钢渣粉和粉煤灰组成的复合胶凝材料的活性指数高于纯钢渣粉和粉煤灰的活性指数。 Abstract: The main characteristics of four kinds of steel slag powder and influence on the strength of cement mortar were studied by using Panzhihua steel slag as the main raw material. At the same time, the effect of different amount of steel slag powder on the strength of cement mortar was studied. The influence of the composite cementitious material composed of steel slag powder and fly ash on the strength of cement mortar was also studied. The results showed that when the amount of steel slag powder was 30%, surface area increased as particle size of steel slag decreased and the activity index increased. For the steel slag powder whose average particle size is 21.36μm and surface area is 450.8m2/kg, the dosage was not more than 10%, the 28d activity index was greater than 100%. However, the strength of cement mortar decreased as amount of steel slag powder increased. The activity index of composite cementitious material composed of steel slag powder and fly ash was higher than that of pure steel slag powder and fly ash.

摘要：以小于4.75mm的矿渣颗粒为集料，以P·O 42.5R水泥为胶凝材料，辅以高效减水剂，用静压压制的成型工艺制备了水泥基声屏障，分析讨论了材料的抗压强度以及水灰比、成型工艺、材料厚度对其吸声性能的影响。结果表明，抗压强度随水灰比的增大而先增大后减小，随成型压力的增大而增大；吸声系数随着水灰比的增大而先增大后减小，随着成型压力的增大而降低；其降噪系数随着材料厚度增加而先增大后减小。当抗压强度达到13.6MPa、材料厚度8cm时，材料的降噪系数为0.65，500Hz、630Hz、800Hz、1000Hz四个频率的平均吸声系数为0.768，可以作为铁路声屏障材料。 Abstract: Using the size below 4.75mm of slag particles as aggregate and the P·O 42.5R cement as cementitious material, with adding superplasticizer, the cement-based sound barrier materials were prepared by compression molding process of static pressure. The compressive strength of materials and the effects of water-cement ratio, molding process, materials thickness on the sound-absorption property were discussed. The results showed that the compressive strength of materials increased first then decreased with the increase of water-cement ratio, and increased with the increase of molding pressure. The sound absorption coefficient of soundbarrier materials increased first then decreased with the increase of water-cement ratio, and decreased with the increase of molding pressure. The noise reduction coefficient increased first then decreased with the increase of materials thickness. When the 28d compressive strength at 13.6MPa and the materials thickness at 8cm, its noise reduction coefficient was 0.67, and the average sound absorption coefficient of four frequency at 500Hz、630Hz、800Hz、1000Hz was 0.768. It could be applied as railway sound-absorbedbarrier materials.

摘要：研究了玄武岩纤维的长径比和掺量对新拌混凝土的工作性能以及硬化体力学性能的影响，通过扫描电镜（SEM）观察了纤维在混凝土中的分散情况。结果表明，纤维的加入会降低新拌混凝土的工作性能；玄武岩纤维可以显著提高混凝土的抗折、劈裂抗拉强度，但对抗压强度的影响较小，并且纤维的长径比和掺量的变化将改变混凝土的力学性能。12mm纤维对混凝土的抗压和劈裂抗拉强度增长最显著，分别为-12.2%~8.4%和5.4%~11.5%。18mm纤维对混凝土的抗折强度增长最佳，相比于基准混凝土增长14.3%~17.1%。此外，纤维在混凝土中的分散性随着长径比和掺量的增长而下降。 Abstract: The effect of length-diameter and mixing amount of basalt fibers on the workability of fresh concrete and mechanical property of hardened concrete was studied, and the dispersion of basalt fibers in concrete was observed by using scanning electron microscope(SEM). The results show that the addition of basalt fibers in concrete will reduce the workability, and obviously improve the flexural and splitting strength of fiber reinforced concrete, but has little influence on the compressive strength. Meanwhile, the mechanical property of fibers reinforced concrete will change with the length-diameter and mixing amount of basalt fibers. The fiber has the best reinforcement for the compressive and splitting strength of concrete at the 12mm length, up to -12.2% to 8.4% and 5.4% to 11.5%, respectively. At the 18mm length, the fiber can greatly improve the flexural strength of concrete, up to 14.3% to 17.1%. Moreover, the dispersibility of basalt fibers, in concrete, drops with the increase of the length-diameter and mixing amount.

摘要：在混掺玄武岩纤维与尼龙纤维增强水泥砂浆的基础上掺入硅灰，利用硅灰的火山灰效应和微集料填充效应改善纤维与砂浆的界面性能，充分发挥纤维对砂浆的增强作用。研究了硅灰掺量对纤维砂浆的工作性、抗折强度和剪切黏结强度的影响，并对硅灰在纤维砂浆中的作用机理进行了分析。结果表明，硅灰的掺入能有效改善纤维砂浆的抗折强度和剪切黏结强度，并且能显著提高纤维与砂浆界面的黏结强度，但砂浆的工作性随着硅灰掺量的增加而降低。本试验条件下，硅灰最适宜的掺量为8%。 Abstract: Adding silica fume into the cement mortar reinforced by basalt and nylon fiber, the interface properties of fiber and mortar could be improved by pozzolanic effect and micro-aggregate filling effect of silica fume, so the enhancement effect of fiber on mortar could be significantly enhanced. The effects of silica fume content on workability, flexural strength and shear bond strength of fiber reinforced mortar were studied, and the mechanism of silica fume in fiber mortar was analyzed. The test results showed that silica fume could improve the flexural strength and shear bond strength of fiber mortar effectively. Apart from this, the interface bond strength of fiber and mortar could be improved significantly. However, the workability of mortar was decreased with the increase of silica fume content. The optimum content of silica fume was 8% in this experimental conditions.
