近两年来,喷射钢纤维混凝土被用于一些重要的土建工程,其中包括香港汇丰银行55000多平方米的钢结构复盖层;德贝(Derby)中央下水道约950立方米的倒拱修理,卡尔辛登(Carsigton)输水隧洞“D”入口处1.7公里以上的衬砌。这些工程的共同点是采用了含量为3～5%(按重量计)的不锈钢熔拔钢纤维来增强混凝土。在英国,首先将熔拔钢纤维应
In the last two years, jetted steel fiber reinforced concrete has been used in some important civil works, including more than 55,000 square meters of steel cladding at HSBC in Hong Kong, about 950 cubic meters of inverted arch repairs at Derby Central Sewers, Linings over 1.7 km at the entrance to Carsigton Water Tunnel “D”. What these projects have in common is the use of 3 to 5% by weight stainless steel drawn steel fibers to reinforce the concrete. In the UK, the first step will be to melt the steel fibers
