研究了混凝土帆布的拉伸试验,制作了5种试件,包括纯帆布及浇水成型3d,7d,14d和28d的混凝土帆布,用于进行了抗拉伸试验。通过试验得到了混凝土帆布在经线和纬线两个方向上的拉伸应力-应变曲线和破坏图案,分析对比经向和纬向,得出纬线方向的抗拉性能明显优于经线方向;拉伸性能很大程度上受外织物基材的影响。 Tensile test of concrete canvas was studied. Five specimens were made, including pure canvas and water-forming concrete canvas for 3d, 7d, 14d and 28d for tensile test. The tensile stress-strain curves and failure patterns of concrete canvas in both warp and weft directions were obtained through experiments. The warp and weft directions of warp and weft were compared, and the tensile properties in the weft direction were obviously better than those in the warp direction. The tensile properties Affected to a large extent by the outer fabric substrate.
