摘要
在5~10 mm碎石掺量为300 kg/m 3条件下,研究了河砂取代不同石英砂量对所制超高性能混凝土性能的影响。结果表明:当钢纤维体积掺量为1.5%、河砂取代石英砂300 kg/m 3时,所制UHPC(Ultra High Performance Concrete,超高性能混凝土)试样扩展度为560 mm,28 d抗折、抗压强度可达23.8 MPa、126.2 MPa。
When the content of 5~10 mm gravel is 300 kg/m 3,the effect of river sand replacing different quartz sand on the performance of ultra-high performance concrete was studied.The results showed that:when the volume content of steel fiber is 1.5%and river sand replaces quartz sand by 300 kg/m 3,the extensibility of the UHPC sample prepared is 560 mm,the 28 day flexural and compressive strength can reach 23.8 MPa and 126.2 MPa.
