摘要：研究了矿渣、粉煤灰以及热等离子技术处理城市垃圾后的熔融残渣（MWTPT）替代10%的水泥对泡沫混凝土性能的影响，并通过XRD、水化热和SEM方法分析了MWTPT的作用机理。结果表明：MWTPT可以作为矿物掺合料替代水泥制备泡沫混凝土；掺MWTPT泡沫混凝土的抗压强度在后期优于掺粉煤灰的泡沫混凝土，抗折强度在早期优于掺矿渣泡沫混凝土和掺粉煤灰泡沫混凝土；与掺粉煤灰泡沫混凝土相比，掺MWTPT泡沫混凝土的7 d、15 d抗折强度分别提高了19.1%、31.8%。 Abstract: The effects of slag, fly ash and the municipal waste residues after treated by thermal plasma technology(MWTPT) replacing 10% cement on the performance of foamed concrete were studied, and the mechanism of MWTPT was analyzed by XRD, hydration heat and SEM. The results show that MWTPT can be used as mineral admixture instead of cement to prepare foamed concrete. The compressive strength of the foamed concrete with MWTPT is better than that of the foamed concrete with fly ash in the later stage, and the flexural strength is better than that of the foamed concrete with slag and the foamed concrete with fly ash in the early stage. The 7 d and 15 d flexural strength of the foamed concrete with MWTPT are 19.1% and 31.8% higher than those of the foamed concrete with fly ash respectively.

Abstract: The effects of slag, fly ash and the municipal waste residues after treated by thermal plasma technology(MWTPT) replacing 10% cement on the performance of foamed concrete were studied, and the mechanism of MWTPT was analyzed by XRD, hydration heat and SEM. The results show that MWTPT can be used as mineral admixture instead of cement to prepare foamed concrete. The compressive strength of the foamed concrete with MWTPT is better than that of the foamed concrete with fly ash in the later stage, and the flexural strength is better than that of the foamed concrete with slag and the foamed concrete with fly ash in the early stage. The 7 d and 15 d flexural strength of the foamed concrete with MWTPT are 19.1% and 31.8% higher than those of the foamed concrete with fly ash respectively.
