铁砂微膨胀混凝土技术研究

Study on Technology of Ferro-sand Micro-expansion Concrete

近年来铁砂在国内部分地区的预拌混凝土搅拌站中的应用已经开展,经过大量工程包括地铁工程、奥运工程等重要工程的实践检验,应用技术日趋成熟。但国内尚无专门的关于铁砂混凝土应用技术的国家标准或行业标准。

In recent years,the application of iron sand in the ready-mixed concrete stations in some areas of China has been carried out.After the practical test of a large number of projects,including the subway project,Olympic project and other important projects,the application technology has become increasingly mature.But there is no special national standard or industry standard about the application technology of iron sand concrete in China.
