摘 要:研究了PVA纤维长度和体积掺量对轴心抗压强度和抗折强度的影响,并采用灰色理论模型分析了轴心抗压强度和抗折强度随龄期的变化规律。结果表明:PVA纤维的掺入在一定程度上改善了混凝土的轴心抗压强度和抗折强度;非等时距GM(1,1)模型的预测精度较高。
Abstract: The effects of PVA fiber length and volume content on the axial compressive strength and flexural strength were studied, and the gray theory model was used to analyze the variation of axial compressive strength and flexural strength with age. The results show that PVA fiber can improve the axial compressive strength and flexural strength of concrete to a certain extent, and the non-equal interval GM (1,1) model has high prediction accuracy.
