长运距C50钢纤维混凝土配合比设计与工程实践

The mix proportion design and engineering practice of C50 steel fibre concrete after long-distance transportation

通过试验确定C50钢纤维混凝土配合比,在克服高温与长距离运输(运输时间最长达2h30min)的情况下使混凝土到现场坍落度及和易性等仍满足施工要求,并取得良好的应用效果。

Determine the mix proportion of C50 concrete through test, make sure the good workability in the field and good applied effect against the influence of high--temperature and long distance transportation.
