摘要：研究了不同掺量的锂渣粉和磷渣粉分别单掺和复掺对再生混凝土抗压强度和抗氯离子渗透性能的影响。结果表明：与空白组试件相比，单掺锂渣粉或磷渣粉试件的7 d、14 d和28 d抗压强度变化幅度最高不超过7.7%；与锂渣粉和磷渣粉分别单掺相比，二者复掺对再生混凝土的7 d抗压强度影响不大，但明显提高了14 d、28 d抗压强度；单掺和复掺锂渣粉和磷渣粉试件的抗氯离子渗透性能均较空白组试件好，其中，复掺锂渣粉和磷渣粉试件的抗氯离子渗透性能介于单掺锂渣粉试件和单掺磷渣粉试件之间，单掺锂渣粉试件的抗氯离子渗透性能最好；再生混凝土中的氯离子在环境氯离子浓度较低时以物理吸附和化学结合为主，而在环境氯离子浓度较高时以化学结合为主；氯离子总结合能力随着环境氯离子浓度的增加而下降；复掺20%锂渣粉与10%磷渣粉试件的氯离子总结合能力相对最好。 Abstract: The effects of different amounts of lithium slag powder and phosphorus slag powder on the compressive strength and resistance to chloride ion penetration of recycled concrete were studied. The results show that, compared with the blank group, the compressive strength of the specimens mixed with lithium slag powder or phosphorus slag powder at 7 d, 14 d and 28 d has the highest change range of not more than 7.7%. Compared with single addition of lithium slag powder or phosphorus slag powder, their combination has little effect on the 7 d compressive strength of recycled concrete, but significantly improves the 14 d and 28 d compressive strength. The resistance to chloride ion penetration of the specimens with lithium slag powder and phosphorus slag powder is better than that of the blank group. Among them, the resistance to chloride ion penetration of the specimens mixed with lithium slag powder and phosphorus slag powder is between that of the specimens with single lithium slag powder or single phosphorus slag powder, and the resistance to chloride ion penetration of the specimens with single lithium slag powder is the best. The chloride ion in recycled concrete is mainly physical adsorption and chemical binding when the environmental chloride ion concentration is low, while the chloride ion is mainly chemical binding when the environmental chloride ion concentration is high. The total chloride ion binding capacity decreases with the increase of the environmental chloride ion concentration. The total chloride ion binding capacity of the specimen mixed with 20% lithium slag powder and 10% phosphorus slag powder is relatively best.

Abstract: The effects of different amounts of lithium slag powder and phosphorus slag powder on the compressive strength and resistance to chloride ion penetration of recycled concrete were studied. The results show that, compared with the blank group, the compressive strength of the specimens mixed with lithium slag powder or phosphorus slag powder at 7 d, 14 d and 28 d has the highest change range of not more than 7.7%. Compared with single addition of lithium slag powder or phosphorus slag powder, their combination has little effect on the 7 d compressive strength of recycled concrete, but significantly improves the 14 d and 28 d compressive strength. The resistance to chloride ion penetration of the specimens with lithium slag powder and phosphorus slag powder is better than that of the blank group. Among them, the resistance to chloride ion penetration of the specimens mixed with lithium slag powder and phosphorus slag powder is between that of the specimens with single lithium slag powder or single phosphorus slag powder, and the resistance to chloride ion penetration of the specimens with single lithium slag powder is the best. The chloride ion in recycled concrete is mainly physical adsorption and chemical binding when the environmental chloride ion concentration is low, while the chloride ion is mainly chemical binding when the environmental chloride ion concentration is high. The total chloride ion binding capacity decreases with the increase of the environmental chloride ion concentration. The total chloride ion binding capacity of the specimen mixed with 20% lithium slag powder and 10% phosphorus slag powder is relatively best.
