| 摘 要： | 进行了不同温度下自密实混凝土、掺加聚丙烯纤维的自密实混凝土、高强混凝土的抗压强度及应力-应变曲线的非持荷试验研究,分析了抗压强度、应力-应变关系随温度的发展变化规律,基于试验结果给出了相应的应力-应变曲线方程,并与普通混凝土、高强、高性能混凝土研究成果进行了对比分析.为高温下自密实混凝土本构模型的建立奠定了基础,也为自密实混凝土结构的设计和分析提供了试验依据. |
| 关 键 词： | 自密实混凝土 高温 抗压强度 应力-应变关系 |

| Abstract: | An unstressed test was made to study the compressive strength and stress strain curve properties of self compacting concrete (SCC), self compacting concrete with addition of polypropylene fiber (PPF), high strength concrete (HSC) under different temperatures.The relationship between compressive strength, stress strain curve and temperature of self compacting concrete was revealed.Stress strain curve function was obtained based on the experiment results, and compared with those of normal concrete (NC), high strength concrete, high performance concrete (HPC). The research results are helpful for for the establishment of constitutive model at high temperature and contributes to the design and analysis of self compacting concrete structure. |
| Keywords: | self compacting concrete high temperature compressive strength stress strain curve |
