Chlorine Ion Penetration Resistance of Concretes Containing Super-Fine Limestone Powder
The influence of limestone powder, air-entraining agent and water binder ratio on chlorine ion (Cl-) penetration resistance of concretes was investigated by rapid Cl- penetration tests. The results show that the fineness of limestone powder is a key factor to Cl- penetration resistance of concrete. It can improve Cl- penetration resistance by introducing super fine limestone powder into concrete. Cl- penetration resistance of concrete increases as curing time increases. The concrete with lower water binder ratio has better Cl- penetration resistance. The introduction of air-entraining agent into concrete can enhance Cl- penetration resistance by improving micro pores structure. The optimum mixing amount is 0.3‰.
