摘要
钢纤维喷射混凝土作永久衬砌 ,在集团公司首次应用 ,既加快施工进度 ,又降低成本 ,显著改善了混凝土的抗裂性能、延性、韧性及抗冲击性能 ,是一种新型复合材料 ,是集团公司在新材料领域应用的一次飞越。
The application of steel fiber shotcrete as permane nt lining had been utilized for the first time by the Second Railway Engineering B ureau. Not only the construction speed was quickened, but also the construction cost was reduced. The anti-crack property, ductility, toughness and anti-shock properties were improved remarkably. It is a new-type composite materials used by the Bureau, having important meaning in the application scope of the new mat erials.
