    摘要:通過試驗測試植物纖維(5%秸稈纖維)頁巖燒結磚在不同玄武巖纖維摻量下的抗壓強度、導熱系數、顯氣孔率、吸水率、體積密度等性能,分析玄武巖纖維摻量對植物纖維頁巖燒結磚力學及物理性能的影響規律。結果表明:隨著玄武巖纖維摻量增加,頁巖燒結磚的抗壓強度逐漸提高,導熱系數及體積密度逐漸降低,顯氣孔率及吸水率變化幅度小且無明顯規律性。
    關鍵詞:頁巖;秸稈;玄武巖纖維;吸水率;抗壓強度

    Abstract:By testing the compressive strength,thermal conductivity,apparent porosity,water absorption and volume density of plant fiber (5% straw fiber) shale sintered brick with different content of basalt fiber,the paper analyzes the influence rule of different content of basalt fiber on mechanical and physical properties of plant fiber shale sintered bricks. The experimental results show that when the content of basalt fiber increases,the compressive strength also increases. At the same time,the thermal conductivity and volume density gradually decreased. The apparent stomatal rate and water absorption rate had little variation and no obvious regularity.
    Key words:shale,straw,basalt fiber,water absorption,compressive strength
