    摘 要:以攀鋼鋼渣為主要原料,研究了四種不同細度鋼渣粉的主要特性及其對水泥膠砂強度的影響,同時研究了不同摻量鋼渣粉和鋼渣粉與粉煤灰組成的復合膠凝材料對水泥膠砂強度的影響。結果表明,在鋼渣粉摻量為30%時,鋼渣粒度越細,比表面積越大,活性指數越高;平均粒徑為21.36μm,比表面積為450.8m2/kg的鋼渣粉在摻量不大于10%時,28d活性指數可大于100%,但進一步增加摻量后水泥膠砂強度不斷降低;鋼渣粉和粉煤灰組成的復合膠凝材料的活性指數高于純鋼渣粉和粉煤灰的活性指數。 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.

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:研究了玄武巖纖維的長徑比和摻量對新拌混凝土的工作性能以及硬化體力學性能的影響,通過掃描電鏡(SEM)觀察了纖維在混凝土中的分散情況。結果表明,纖維的加入會降低新拌混凝土的工作性能;玄武巖纖維可以顯著提高混凝土的抗折、劈裂抗拉強度,但對抗壓強度的影響較小,并且纖維的長徑比和摻量的變化將改變混凝土的力學性能。12mm纖維對混凝土的抗壓和劈裂抗拉強度增長最顯著,分別為-12.2%~8.4%和5.4%~11.5%。18mm纖維對混凝土的抗折強度增長最佳,相比于基準混凝土增長14.3%~17.1%。此外,纖維在混凝土中的分散性隨著長徑比和摻量的增長而下降。 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:在混摻玄武巖纖維與尼龍纖維增強水泥砂漿的基礎上摻入硅灰,利用硅灰的火山灰效應和微集料填充效應改善纖維與砂漿的界面性能,充分發揮纖維對砂漿的增強作用。研究了硅灰摻量對纖維砂漿的工作性、抗折強度和剪切黏結強度的影響,并對硅灰在纖維砂漿中的作用機理進行了分析。結果表明,硅灰的摻入能有效改善纖維砂漿的抗折強度和剪切黏結強度,并且能顯著提高纖維與砂漿界面的黏結強度,但砂漿的工作性隨著硅灰摻量的增加而降低。本試驗條件下,硅灰最適宜的摻量為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.
