摘要
初步研究了纤维梯度分布对纤维增强混凝土及砂浆力学性能的影响。结果表明 ,采用分层成型、纤维梯度分布、使纤维的分布更符合受力状态 ,与纤维均匀分布相比可以明显提高混凝土与砂浆的抗折和抗压强度 。
In this paper, the effects of the fiber gradient distribution on the strength of steel-fiber-reinforced concrete and glass-fiber-reinforced mortar are studied. The test results shown that the flexural and compressive strength of fiber gradient distributed concrete and mortar (FGDCM) by means of multi-layer vibrating formation have been obviously improved, their strengths are higher than those of fiber homogeneous distributed concrete and mortar (FHDCM). For getting the same strength, the fiber volume mixed in HGDCM is smaller than that mixed in FHDCM.
