竹纤维与水泥等无机材料复合制备的加气混凝土，在相同工艺条件下会出现表观密度的下降。以相同表观密度为基准，通过竹纤维复合加气混凝土可以成为增强抗压强度和提高材料的吸音系数的方法之一。研究表明：当慈竹纤维含量达到7．17％时、毛竹纤维含量为5．94％时、绿竹纤维含量为7．93％时，增强效果达到峰值。三种竹纤维中慈竹纤维增强效果最好：抗压强度提高了12．5％；绿竹纤维复合增强抗压强度9．4％；毛竹纤维复合增强7．9％。另一方面，不同竹纤维复合的加气混凝土的吸音系数均有不同程度的提高。

Under the same manufacture conditions, aerated concrete made from bamboo fibre and cement has a lower apparent density than that made from cement only. Consequently, one of these formers would have a higher compression strength and sound absorption coefficient than the latter base on same apparent density. The results indicated that 7.17% Omei Mountain Bamboo (Bambusae Omeiensis) fiber, 5. 94% Moso bamboo (Phyllostachys edulis) (Carr.) H. de L. ) fiber, green bamboo (Bambusa oldhamii Munro) fiber was the optimum a- mount that resulted in maximum increase in compression strength and sound absorption ability. Adding bamboo fibers increased compres- sion strength by 12.5%, 9.4% and 7.9%. Same time, the absorption coefficients of samples are raised respectively.
