FC料对氯离子渗透与抗碳化性能影响的研究

Study on effect of FC-admixture on anti_Cl^--permeability and anti-carbonation

通过氯离子渗透试验和碳化试验 ,研究了FC料对混凝土氯离子渗透性和碳化性能的影响 .采用FC料等量取代 36%的水泥 ,作为混凝土的组分 ,混凝土的抗氯离子渗透能力提高 2 5倍以上 ,同期抗碳化能力提高 1 0倍以上 .使用FC料等量取代水泥 ,具有掺量大、性能好的特点 ,能够实现绿色高性能混凝土 (GHPC)的目标 .

In the experiments of Cl-_permeability and the anti_carbonation of concrete, the effect of FC_admixture on them has been studied. When 36% of cementis replaced by the same amount of FC_admixture which used as composition of concrete, the performance of anti_carbonation and Cl-_permeability is greatly increased(they are more than 10 times and 2 5 times under the circumstance at same time).Its total amount is large and the quantility is excellent. Thus, the goal of Green High Performance Concrete can be reached by FC admixture.
