矿粉和粉煤灰可以有效提高混凝土的抗氯离子渗透性能，且掺量、龄期是影响混凝土抗氯离子渗透性的主要因素。大量试验表明：混凝土的抗氯离子渗透性能随着矿粉、粉煤灰单掺掺量增多、试验龄期延长而增强；在龄期和掺量相同条件下，矿粉、粉煤灰双掺混凝土的抗氯离子渗透性能最好，矿粉单掺次之，粉煤灰单掺最差；试验龄期对粉煤灰单掺混凝土的抗氯离子渗透性能影响最大，矿粉、粉煤灰双掺次之，对矿粉单掺混凝土的抗氯离子渗透性能影响最小。

Slag and fly ash can improve concrete resistance to chloride ion penetration,and the dosage,age is the main factor affecting the concrete resistance to chloride ion penetration.with the in-crease of slag,fly ash,test age extended,resistance to chloride ion permeability of concrete reinforced;under the same conditions,age and dosage,it is the best when adding both slag power and fly ash,it is good when adding only slag power,and it is poor when adding only fly ash;for the influences of the test age on the concrete’s resistance to chloride ion penetration,it is maximum when adding only fly ash,it is moderate when adding both slag powder and fly ash,and it is minimum when adding only slag power.
