| 摘 要： | 通过不同配合比的纤维矿渣微粉混凝土在3 d、7 d、14 d、28 d、56 d和90 d的抗压试验,研究矿渣微粉掺量、纤维掺量、试件尺寸以及龄期对混凝土抗压强度的影响。结果表明,矿渣微粉的加入提高了混凝土各龄期的强度,同时强度的提高和钢纤维的加入使混凝土的尺寸效应更加明显。在分析试验结果的基础上,提出了考虑龄期、纤维掺量和矿渣微粉掺量影响的纤维矿渣微粉混凝土抗压强度计算公式。

| Abstract: | The influence of slag powders dosage,fiber dosage,specimen sizes and ages on compressive strength had been studied through the tests of fiber reinforced slag concrete with different mixture ration at the ages of 3 d,7 d,14 d,28 d,56 d and 90 d.The results indicate that the addition of slag powder increases the strength of concrete at every age.Furthermore,the dimensional effect of concrete becomes more distinct with the increase of concrete strength and the addition of steel fiber in concrete.Finally,the un... |
