稻草纤维混凝土性能研究

Study on properties of straw fiber reinforced concrete

通过对同一混凝土配合比不同掺量、不同形状稻草纤维混凝土的物理力学性能进行试验,分析出同一混凝土配合比不同掺量、不同形状稻草纤维对混凝土的抗压强度、劈裂抗拉强度、抗折强度、抗冲击、经济方面等性能的变化规律,试验结果表明:加入稻草纤维后,混凝土的抗压强度、劈裂强度、抗折强度有所下降,但是其抗冲击性能有所提高;与其他传统纤维相比,稻草纤维比较经济使用。因此针对稻草纤维混凝土性能的研究具有一定的意义。

According to the experiment which is about physical and mechanical properties of straw fiber concrete under different dosage and different shapes circumstances using the same ratio, the effect for straw fiber concrete under different dosage and different shapes cir- cumstances using the same ratio was got on compressive strength, splitting tensile strength, flexural strength, impact resistance, economy and so on, Test results showed that after joining the straw fibre, concrete compressive strength, splitting strength and flexural strength had declined, but the improvement in impact resistance; compared with traditional fiber, more economic use of straw fiber.Research on properties of straw fiber concrete therefore had certain significance.
