Harex钢纤维在国外用于混凝土中已相当广泛,而在国内城市道路中应用尚属空白。钢纤维用于修筑道路可大幅度减薄路面厚度、加大缩缝间距、缩短工期、提高平整度、延长使用寿命等,尤其是Harex钢纤维在混凝土中分散性很好,且施工简便。 由于Harex钢纤维的上述优点,1994年10月,我们在浦东新区浦电路改造中应用了Harex钢纤维,并进行了以下试验研究:a.
Harex steel fiber used in foreign countries has been quite extensive in the concrete, but the application in the domestic urban roads is still blank. Steel fiber used to build roads can greatly reduce the thickness of the road, increase the shrinkage gap, shorten the construction period, improve the flatness, prolong the service life, especially Harex steel fiber in concrete dispersion is good, and the construction is simple. Due to the above advantages of Harex steel fibers, Harex steel fibers were used in the Pudong New Area Pu Circuit retrofit in October 1994 and the following experimental studies were conducted: a.
