| 摘 要： | 研究了不同水胶比和玄武岩骨料掺量对超高性能混凝土(UHPC)受压力学性能的影响.结果表明:抗压强度随水胶比的增加表现出先增大后减小的趋势,而弹性模量呈持续减小趋势,当水胶比为0.16时,UHPC的抗压强度较佳;掺入粗骨料对UHPC的抗压强度和弹性模量均有较大影响,随着骨料掺量的增加,抗压强度呈现先增加后减小的趋势,弹性...

| Abstract: | The effects of water-to-binder ratio and basalt coarse aggregate on the compressive behavior of ultra-high-performance concrete(UHPC)were investigated.The results show that the compressive strength of UHPC firstly increases and then decreases,while the elastic modulus decreases with the increase of water-to-binder ratio,and the optimum compressive strength is obtained at a water-binder ratio of 0.16.The compressive strength firstly increases and then decreases,while the elastic modulus increases with the increase of coarse aggregate.In addition,a semi-empirical equation considering the parameters of coarse aggregate was also proposed for the prediction of elastic modulus of UHPC,which was validated using the existing literature data. |
