| 摘 要： | 针对目前应用混凝土平板法试验、抗裂系数评价高性能混凝土的抗裂性能过程中,尚存在的不足之处,从吹风起始时间、抗裂系数计算参数选取等角度,对低水胶比粉煤灰混凝土、大掺量磨细矿渣混凝土的抗裂性能进行比较.结果表明:平板法试验时,吹风起始时间对混凝土的表面裂缝状况有显著的影响,在混凝土初凝之前,吹风起始时间越早,混凝土表面出现...

| Abstract: | At present,shortcomings existed in evaluating course of the anti-cracking property of high performance concrete(HPC) with flat test and anti-cracking coefficient.Experiment and studies on the anti-cracking property of fly-ash concrete and concrete with high volume of ground slag at low water to binder ration are carried out.The effects of the beginning time of blow and the choice of calculation conditions of anti-cracking coefficient are discussed in this paper.The results show that an obvious effect on the... |
