| 3 | Behaviors of recycled aggregate concrete-filled steel tubular columns under eccentric loadings显示文摘The paper investigates the behaviors of recycled aggregate concrete-filled steel tubular(RACFST)columns under eccentric loadings with the incorporation of expansive agents.A total of 16 RACFST columns were tested in this study.The main parameters varied in this study are recycled coarse aggregate replacement percentages(0%,30%,50%,70%,and 100%),expansive agent dosages(0%,8%,and 15%)and an eccentric distance of compressive load from the center of the column(0 and 40 mm).Experimental results showed that the ultimate stresses of RACFST columns decreased with increasing recycled coarse aggregate replacement percentages but appropriate expansive agent dosages can reduce the decrement;the incorporation of expansive agent decreased the ultimate stresses of RACFST columns but an appropriate dosage can increase the deformation ability.The recycled coarse aggregate replacement percentages have limited influence on the ultimate stresses of the RACFST columns and has more effect than that of the normal aggregate concretesteel tubular columns. | Vivian W.Y.TAM Jianzhuang XIAO Sheng LIU Zixuan CHEN | 2019 | Frontiers of Structural and Civil Engineering2019，13，3： | 0 |
| 4 | Effect of fly ash and slag on concrete:Properties and emission analyses显示文摘Recycled concrete is a material with the potential to create a sustainable construction industry.However,recycled concrete presents heterogeneous properties,thereby reducing its applications for some structural purposes and enhancing its application in pavements.This paper provides an insight into a solution in the deformation control for recycled concrete by adding supplementary cementitious materials fly ash and blast furnace slag.Results of this study indicated that the 50%fly ash replacement of Portland cement increased the rupture modulus of the recycled concrete.Conversely,a mixture with over 50%cement replacement by either fly ash or slag or a combination of both exhibited detrimental effect on the compressive strength,rupture modulus,and drying shrinkage.The combined analysis of environmental impacts and mechanical properties of recycled concrete demonstrated the possibility of optimizing the selection of recycled concrete because the best scenario in this study was obtained with the concrete mixture M8(50%of fly ash+100%recycled coarse aggregate). | Vivian W.Y.TAM Khoa N.LE Ana Catarina Jorge EVANGELISTA Anthony BUTERA Cuong N.N.TRAN Ashraf TEARA | 2019 | Frontiers of Engineering Management2019，6，3： | 0 |
