木纤维混凝土抗压弯折性能实验研究

The Compressive and Flexural Strengths of Wood-fiber Concrete

研究了木纤维干湿状态对木纤维混凝土抗压强度、弯折强度的影响,对干燥状态和饱和吸水状态下的木屑分别进行试验对比。结果表明,在7%干燥状态下的木屑掺杂进混凝土后,在减少细骨料的情况下混凝土的强度反而增加,为木屑废弃物的综合利用开辟了新的途径。

This research probes into dry and wet states which affect its compressive and flexural strengths of the wood-fiber,and also makes an experimental comparison between the states of dry and saturated sorption.The results show that up to 7% replacement of sand with dry sawdust and the decrease of the quantity of fine aggregate improves the compressive strength and flexural strength of concrete,which provides a new channel for the comprehensive utilization of wood waste.
