| 1 | Properties of Steel Slag and Stainless Steel Slag as Cement Replacement Materials:A Comparative Study显示文摘To enhance the understanding about the utilization of steel slags as a cementitious material, we comparatively studied the chemical, mineralogical and morphological properties of two types of steel slag; basicoxygen-furnace carbon slag(BOF C) and electric-arc-furnace stainless steel slag(EAF S). Moreover, we studied the standard consistency, setting time and the effect of the slag replacement ratios on the fluidity and compressive strength of blended cement mortar. The experimental results showed that BOF C had higher alkalinity, higher pH value and more hydraulic phases than EAF S. Both types of slag showed water reduction effect due to its high fineness. Neat BOF C paste showed flash set and acceleration in the initial setting time of blended cement especially at high slag proportions. However, EAF S prolonged the setting time of blended cement even at low slag proportions. The pH values for blended cement contained 50% BOF C or EAF S were lower than those of pure cement paste. Despite of slag type, compressive strength gradually decreased with increasing slags content. The strength of BOF C mortar was higher than that of EAF S mortar with the same replacement ratio for the same age. Slag activity index demonstrated that BOF C and EAF S conformed to the Chinese National Standard(GB/T 20491-2006) requirements for steel slag as grade one and grade two, respectively. | SALY Fathy GUO Liping MA Rui GU Chunping SUN Wei | 2018 | Journal of Wuhan University of Technology(Materials Science)2018，33，6： | 5 |
| 2 | 养护制度对超高性能纤维增强水泥基复合材料微观结构及宏观性能的影响(英文)显示文摘研究了不同养护制度对超高性能纤维增强水泥基复合材料(UHPFRCC)微观结构和宏观性能的影响,并揭示了用不同的养护制度制备性能符合要求的超高性能纤维增强水泥基复合材料的可能性.制备了一种基准的UHPFRCC,研究了3种养护制度下UHPFRCC的力学性能及短期耐久性能.此外,通过结合运用电子扫描电镜(SEM)和压汞法(MIP),测试了3种养护制度下UHPFRCC的微观结果.研究结果揭示了不同的养护制度对UHPFRCC微观结构的影响以及微观结构对材料宏观性能的影响机制.热养护和蒸汽养护3d与标准养护90 d的UHPFRCC具有相近的力学性能和耐久性.但是,热养护的UHPFRCC具有相对较差的抗氯离子渗透性能. | Saly Fathy 孙伟 | 2014 | Journal of Southeast University(English Edition)2014，30，3： | 3 |
| 3 | 荷载与环境因素耦合作用下超高性能水泥基复合材料的主要性能(英文)显示文摘研究了钢纤维掺量和强度等级对超高性能纤维增强水泥基复合材料(UHPFRCC) 宏观性能的影响及UHPFRCC 在荷载与环境因素耦合作用下的耐久性能. 制备了 3 组不同强度等级(100,150,200 MPa) 和不同纤维掺量 (0%,1%,2%,3%) 的高与超高性能水泥基复合材料,并且测试了其各项力学性能和短期耐久性能. 利用设计的预加载装置,在 UHPFRCC150 试件上施加了应力比为 0. 5 的四点弯曲荷载. 结果表明,随着强度等级的增加,在掺加适量钢纤维掺量的情况下,高与超高性能水泥基复合材料的强度和韧性均明显提高,同时其干燥收缩值降低. 对于加载的试件,钢纤维降低了拉应力对 UHPFRCC 抗氯离子渗透性能的不利影响,并且提高了材料的抗冻融性能. | Saly Fathy 顾春平 孙伟 | 2012 | Journal of Southeast University(English Edition)2012，28，2： | 0 |
