纺织废料再生纤维增强混凝土力学性能的研究

Research on mechanical properties of recycled waste fiber reinforced concrete

对纺织废地毯再生纤维增强混凝土的力学性能进行实验研究.结果表明,含量为20/0的纺织废地毯再生纤维增强混凝土的抗压强力、抗剪切强力和抗弯曲强力等力学性能较普通混凝土有所提高;干燥收缩性以及由此引起的韧性及能量吸收性较普通混凝土均有较大改善.这种混凝土若能得到广泛使用,还可节约资源、保护环境.

A study has been carried out for evaluating the mechanical properties of the reinforced concrete using recycled fibers from used carpets, and it presents that in contrast of traditional concrete, the compressive strength, shearing strength and bending strength are improved and the dry shrinkage, toughness and energy absorption are significantly increased. If this kind of concrete can be widely applied, it is much favorable for saving materials and protecting environment.
