摘要
本文对碳纤维水泥浆体和砂浆的强度和韧性进行了研究。试验结果表明,碳纤维能显著提高水泥浆体的强度和韧性。碳纤维在砂浆中的作用明显低于在净浆中的作用,并且随着砂胶比的增加,碳纤维对砂浆的强度和韧性的改善作用是降低的。
The strength and toughness of carbon fiber reinforced cement paste and mortar were studied and discussed. Experimental results show that carbon fiber can increase the strength and toughness of cement paste significantly, but effect of carbon on mortar is lower than that of cement paste. Moreover, improving in the strength and toughness of carbon fiber mortar decreases as the sandbinder ratio increases.
