采用等体积置换法，将橡胶粉分别按10%、20%、30%、40%、50%取代细集料配制橡胶混凝土，并通过不同掺量的纤维对其进行增强，分析并评价了橡胶混凝土的力学性能、耐磨性能以及抗冲击性能。试验结果表明：纤维增强橡胶混凝土的抗压强度较基准混凝土有大幅度降低，抗折强度以及劈裂强度明显增大；随着纤维和橡胶粉的掺入，混凝土的耐磨性能和抗冲击韧性均有所提高，且随着纤维掺量的增加而增大；当纤维掺量0.9kg/m3左右，橡胶粉体积掺量不超过40%时，混凝土性能最为优异。
採用等體積置換法，將橡膠粉分彆按10%、20%、30%、40%、50%取代細集料配製橡膠混凝土，併通過不同摻量的纖維對其進行增彊，分析併評價瞭橡膠混凝土的力學性能、耐磨性能以及抗遲擊性能。試驗結果錶明：纖維增彊橡膠混凝土的抗壓彊度較基準混凝土有大幅度降低，抗摺彊度以及劈裂彊度明顯增大；隨著纖維和橡膠粉的摻入，混凝土的耐磨性能和抗遲擊韌性均有所提高，且隨著纖維摻量的增加而增大；噹纖維摻量0.9kg/m3左右，橡膠粉體積摻量不超過40%時，混凝土性能最為優異。

The kind of concrete with different content of fiber is prepared using the volume displacement method to replace fine aggregate by the rubber powder of 10%, 20%, 30%, 40%, 50%. The mechanical properties, wear resistance and impact resistance of the fiber reinforced rubber concrete are analyzed and evaluated. The results show that the com≥pressive strength of fiber reinforced rubber concrete significantly reduce compare with normal concrete, while the flexural strength and splitting strength of the fiber reinforced rubber concrete significantly increase; adding fiber and rubber pow≥der can the enhance wear resistance and impact toughness of the concrete, and these properties increase with the increas≥ing content of fiber; When the fiber content is about 0.9kg/m3, the rubber content is less than 40% of fine aggregate(vol≥ume content), the concrete performance is the best.
