不同种纤维混凝土抗冻性能研究

Study on the frost resistance of different fiber reinforced concrete

纤维混凝土的冻融破坏问题是影响耐久性的主要因素之一,因此对纤维混凝土抗冻性的研究至关重要。通过综述国内外学者四种纤维混凝土抗冻性的研究成果,对冻融循环次数,纤维种类、掺量、掺入方式等影响因素进行研究分析,并总结出改善纤维混凝土抗冻性的具体措施。

Fiber concrete freeze-thaw damage problem is one of the main factors affecting the durability,therefore is very important for the research of fiber concrete frost resistance,this paper reviews the research results of scholars at home and abroad,the freezing and thawing cycles,fiber type,dosage and adding method,three kinds of coupling effect and additive,etc.Through analyzing influence factors,and summed up the improvement of fiber concrete frost resistance of concrete measures.
