采用两个基体强度和钢纤维的五种体积掺量进行组合试验,通过方差分析研究钢纤维体积掺量和混凝土基体强度对提高极限弯曲强度和达到极限弯曲强度后一定挠度区间内继续消耗能量影响的显著性,比较钢纤维体积掺量和基体强度不同组合时的增韧效果.研究结果表明:钢纤维体积掺量和基体强度均为影响钢纤维混凝土弯曲韧性的显著因素.
- Abstract:
-
The combination test of two matrix strengths and five volumetric contents of steel fibers was carried out, and the significance of the influence of steel fiber volume content and concrete matrix strength on the continuous energy consumption in a certain deflection interval after improving the ultimate flexural strength and reaching the ultimate bending strength was studied by ANOVA, and the toughening effect of different combinations of steel fiber volume content and matrix strength was compared. The results show that the volume content and matrix strength of steel fiber are significant factors affecting the flexural toughness of steel fiber concrete.
