基于纤维-骨料细观分布的自密实钢纤维混凝土单调和循环压缩性能研究OA北大核心CSTPCD
Cyclic compression performance of SFRSCC based on meso-distribution of fiber-aggregate
自密实钢纤维混凝土(SFRSCC)压缩性能表现和内部组分含量及分散状态均具有显著关联.为探究这种关联特性,定制不同组分配比的SFRSCC拌合物来浇筑制备棱柱体试块,并分别开展单调及循环压缩实验探索其压缩性能特性研究;随后截取每组试块的数个特征截面,采用粗骨料面积占比来描述粗骨料含量,将钢纤维含量及分散情况量化为Voronoi增韧面积统计值,并结合实测数据建立压缩力学特性和内部组分含量及分布特性之间的关联.参考上述关联特性,建立SFRSCC单调和循…查看全部>>
The compressive performance,component content,and dispersion state of self-compacting steel fiber reinforced concrete(SFRSCC)are significantly correlated.To investigate these correlations,SFRSCC prism specimens were prepared using mixtures with different component proportions.Monotonic and cyclic compression tests were conducted to explore the compressive performance characteristics.The coarse aggregate content was described using the percentage of coarse ag…查看全部>>
