摘要:
 为研究高韧性水泥基材料养护龄期与其力学性能之间的关系，对不同纤维掺量的水泥基材料开展抗压、抗折性能试验，测定不同纤维掺量的混凝土在7 d、14 d、28 d、35 d的抗压强度和抗折强度，并与基准混凝土试块对比。结果表明：纤维的掺入能够较好地提高混凝土的力学性能，高韧性水泥基材料的抗压强度和抗折强度与基准混凝土相比差异较大；基体抗压强度增幅不高而抗折性能有较大提高，试验抗折强度最高提高92.32%；高韧性水泥基材料抗压强度与抗折强度均随养护龄期的增加而增大，适当延长养护龄期有利于提高高韧性水泥基材料的工作性能。
Abstract:
 In order to study the relationship between the curing age of high-toughness cementitious composites and its mechanical properties, Non-standards compressive test and folding test were carried out on high-toughness cementititous composites with different fiber parameters. The compressive strength and folding strength of concrete with different fiber content were determined at 7 d, 14 d, 28 d and 35 d, and were contrasted with standard concrete test blocks. The results show that the fiber blending can improve the mechanical properties of concrete．The compressive strength and folding strength of high-toughness cementitious composites are greatly improved compared with ordinary concrete． The compressive strength and folding strength of High Toughness cementitious composites increase with the increase of curing age． Proper extension of curing age is conducive to improving the working performance of high-toughness Cementitious Composites．
