德国研究联合会(DFG)的重点研究计划SPP1182“超高强混凝土的可持续结构”中,对各种超高性能纤维增强混凝土(UHPFRC)复合物的工作性以及抗拉、抗压性能进行了研究。试验研究结果表明,钢纤维的种类、外形比(长度与直径之比)与掺量对UHPFRC达到最大荷载后的承载能力与裂后性能有影响,作者根据UHPFRC的受压变形与裂后抗拉强度间的相关性,提出用计算法来表征此种混凝土的单轴应力-压缩变形曲线。
The workability and tensile and compressive properties of various ultra high performance fiber reinforced concrete (UHPFRC) composites have been studied in the key research project SPP1182 “Sustainable Structure of Super High Strength Concrete” by the German Research Federation (DFG) Study. Experimental results show that the type of steel fiber, the shape ratio (length to diameter ratio) and dosage of UHPFRC maximum load carrying capacity and post-crack performance have an impact, the author according to UHPFRC compression deformation and tensile strength after fracture Strength of the correlation between proposed calculation method to characterize this kind of concrete uniaxial stress - compression deformation curve.
