摘要
研制了一种无约束条件下测量混凝土早龄期收缩的新方法———电涡流法.电涡流法能准确地测定出从浇筑起3 d内混凝土早龄期的收缩变化,并可评估纤维及有关组分对混凝土早龄期收缩变化的影响.电涡流法有望在工程实践中得到推广应用.
A new eddy current method is proposed which can be applied for concrete early age shrinkage（3 d） measurement without constraint conditions. By this method, the concrete shrinkage can be tested accurately during concrete early age from pouring. It also can help evaluate the effects of fiber and other materials on the concrete early age shrinkage and this method can he easily applied on the construction site.
