when the steel fiber volume fraction is higher than 3.5%, its compressive strength decreases, the splitting tensile strength increases slightly, however, its flexural strength increases obviously.
当钢纤维体积含量超过3.5% 后,活性粉末混凝土抗压强度下降,劈拉强度略有提高,而抗折强度仍有明显的提高。
the effects of the base concrete strength, steel fiber volume fraction and steel fiber forms on the coefficients of flexural toughness and the variation factors of flexural resistance are analyzed.
目前,大掺量粉煤灰混凝土断裂韧度的研究正逐步深入,但尚未发现关于异型塑钢纤维、灰胶比和水胶比对大掺量粉煤灰混凝土的强度和断裂韧度影响的研究。
the effect of long-rod projectile「s striking velocity and steel fiber volume fraction on sfrc」s anti-penetration performance was investigated, respectively.
分别研究了桿弹着速和钢纤维体积含量对钢纤维混凝土抗侵彻性能的影响。
