引用本文摘 ? 要：研究了玄武巖纖維摻量對全再生粗骨料混凝土抗壓和抗折強度、破壞形態、單軸受壓應力-應變曲線的影響。結果表明：摻入玄武巖纖維后，試件的抗壓強度提高，受壓破壞時的整體性更好；隨著玄武巖纖維摻量的增加，試件的抗折強度逐漸增大，所有抗折試件均為峰值后脆性破壞；隨著玄武巖纖維摻量的增加，試件的峰值應力先增大后減小，峰值應變、靜壓彈性模量和軸壓韌性比總體均呈增大趨勢。 Abstract: The effects of basalt fiber content on the compressive and flexural strength, failure mode and uniaxial stress-strain curve of fully recycled coarse aggregate concrete were studied. The results show that after adding basalt fiber, the compressive strength of the specimen is improved and the integrity of compression failure is better. With the increase of basalt fiber content, the flexural strength of the specimens increases gradually, and all flexural specimens are brittle failure after peak value. With the increase of basalt fiber content, the peak stress increases first and then decreases, and the peak strain, static elastic modulus and axial compressive toughness ratio increase as a whole.
