chinois. 通过平板试验,研究杜拉纤维混凝土骨料级配的分形特征及纤维掺量对其早期表面塑性开裂的影响两个方面。结果表明,随着骨料级配分维值的逐渐增大,混凝土早期塑性开裂的越严重;掺入杜拉纤维能有效抑制混凝土裂缝的产生。

According to the slab test,research on the early surface plastic cracking of Dura fiber concrete and its two influence factors： aggregate gradation fractal characteristics and fiber content.The results show that,with the gradually increasing of aggregate gradation fractal dimension,the early plastic cracking of concrete is more serious;adding Dura fiber can effectively control the concrete cracks.
