玄武岩纤维对自密实再生混凝土性能的影响
Impact of basalt fiber on mechanical properties and workability of self-compacting recycled coarse aggregate concrete
摘要
Abstract
To investigate the influence of basalt fiber on the performance of self-compacting recycled coarse aggregate concrete(SCRCAC),the workability,mechanical properties,and microstructure of self compacting recycled concrete with basalt fiber volume fraction of 0-0.5%were tested by controlling variables.The effects of basalt fiber volume fraction on the slump flow and segregation ratio of self compacting recycled aggregate concrete were obtained,and the reinforcement mechanism of basalt fiber on the matrix of self compacting recycled concrete was revealed.The results show that incorporation of basalt fiber significantly increases the viscosity,thereby reduces its workability.Furthermore,the SCRCAC containing 0.25%basalt fiber by volume exhibits the best mechanical performance.However,excessive fiber content leads to a decline in mechanical properties,primarily due to reduced anti-segregation capacity.关键词
