The conventional extension degree cannot fully reflect the construction performance of ultra-high performance concrete (UHPC), and it should be supplemented by the rheological properties. However, the proprietary equipment for the measurement of rheological properties is expensive, which is inconvenient to be directly used on the construction site. Therefore, 18 kinds of mix proportions of UHPC were prepared via changing the water-to-binder ratio and superplasticizer dosage. In this work, the flow and rheological parameters of various mix proportions of UHPC were obtained via testing the extension degree, characteristic time of extension degree (i.e., the time required for extension diameter of 0.7 and 0.8 times), rheological behavior, and mechanical properties after curing of the corresponding mix proportions. Finally, a relationship between fluidity and rheology of fresh UHPC (without steel fibers), which the mechanical properties belong to UHPC (with steel fibers), was established. The results show that the Bingham model can be used to describe the rheological behavior of fresh UHPC. The proposed characteristic time of extension degree index has a relatively high test accuracy. The rheological parameters of fresh UHPC can be obtained from the flowability-rheology relationship established. It is indicated that the calculated data by the proposed method agree well with the experimental results.

传统的扩展度已不能全面反映超高性能混凝土（UHPC）的施工性能，必须辅之以流变性能。但流变性能测试的专有设备较昂贵，不便工地直接采用。为此，改变水胶比和减水剂掺量，制备了18种配合比。通过对相应配合比进行扩展度、特征扩展时间（扩展直径为0.7和0.8倍扩展度所需时间）、流变参数测试，以及固化后的力学性能测试，得到多种配合比的流动参数与流变参数，建立了力学性能属于UHPC（掺钢纤维）的素UHPC（不含钢纤维）流动性与流变性关系。结果表明：可以采用Bingham模型描述素UHPC的流变行为；提出的特征扩展时间指标，测试精度相对较高；新拌素UHPC流变参数可以通过所建立的流动-流变关系得出，计算值与试验值吻合较好。

摘要
收起

传统的扩展度已不能全面反映超高性能混凝土（UHPC）的施工性能，必须辅之以流变性能。但流变性能测试的专有设备较昂贵，不便工地直接采用。为此，改变水胶比和减水剂掺量，制备了18种配合比。通过对相应配合比进行扩展度、特征扩展时间（扩展直径为0.7和0.8倍扩展度所需时间）、流变参数测试，以及固化后的力学性能测试，得到多种配合比的流动参数与流变参数，建立了力学性能属于UHPC（掺钢纤维）的素UHPC（不含钢纤维）流动性与流变性关系。结果表明：可以采用Bingham模型描述素UHPC的流变行为；提出的特征扩展时间指标，测试精度相对较高；新拌素UHPC流变参数可以通过所建立的流动-流变关系得出，计算值与试验值吻合较好。

The conventional extension degree cannot fully reflect the construction performance of ultra-high performance concrete (UHPC), and it should be supplemented by the rheological properties. However, the proprietary equipment for the measurement of rheological properties is expensive, which is inconvenient to be directly used on the construction site. Therefore, 18 kinds of mix proportions of UHPC were prepared via changing the water-to-binder ratio and superplasticizer dosage. In this work, the flow and rheological parameters of various mix proportions of UHPC were obtained via testing the extension degree, characteristic time of extension degree (i.e., the time required for extension diameter of 0.7 and 0.8 times), rheological behavior, and mechanical properties after curing of the corresponding mix proportions. Finally, a relationship between fluidity and rheology of fresh UHPC (without steel fibers), which the mechanical properties belong to UHPC (with steel fibers), was established. The results show that the Bingham model can be used to describe the rheological behavior of fresh UHPC. The proposed characteristic time of extension degree index has a relatively high test accuracy. The rheological parameters of fresh UHPC can be obtained from the flowability-rheology relationship established. It is indicated that the calculated data by the proposed method agree well with the experimental results.
