摘要/Abstract

摘要： 以强度最大、刚度适宜为原则确定水泥中粉煤灰最佳质量分数,设置不同水泥和再生砖骨料质量分数以及养护龄期为控制参数,对15种不同配合比下的再生砖混水稳材料(recycled brick mix water stabilizing material, RBSM)进行力学性能研究,采用熵权TOPSIS(technique for order preference by similarity to ideal solution)模型对RBSM的综合性能进行评价,并得出最优参数。结果显示,(1)早期劈裂强度和无侧限抗压强度随着粉煤灰质量分数的增加呈先增后降趋势,在质量分数为10%时达到峰值,抗压回弹模量随着粉煤灰质量分数的增加而增加,最终确定粉煤灰在水泥中的最佳质量分数为10%;(2)RBSM的最优含水率随再生砖骨料质量分数的增加逐渐增大,最大干密度则随之降低;(3)养护初期,RBSM的劈裂强度随再生砖骨料质量分数的增加逐渐降低,无侧限抗压强度则呈先增加后减小的趋势,并在质量分数为50%时达到峰值,随着养护龄期的增加,RBSM的力学强度均有提升;(4)通过熵权TOPSIS理论,得到最佳水泥和再生砖骨料质量分数。最终推荐粉煤灰在水泥中的质量分数为10%、水泥在再生砖混水稳材料中的质量分数为7%、再生砖骨料在再生砖混骨料中的质量分数为50%作为再生砖混水稳材料最佳配比。

Abstract: The optimal mass fraction of fly ash was determined based on the principles of maximum strength and appropriate stiffness, with cement and recycled brick aggregate mass fractions and curing age set as control parameters. Mechanical properties of 15 recycled brick mix water stabilizing materials(recycled brick mix water stabilizing material, RBSM)under different mix designs were investigated. The comprehensive performance of RBSM was evaluated using the entropy-weighted TOPSIS(technique for order preference by similarity to ideal solution)model, yielding optimal values for each parameter. Results indicate,(1)Early-age splitting tensile strength and unconfined compressive strength first increase then decrease with rising fly ash content, peaking at 10% mass fraction. Compressive rebound modulus increases with fly ash content, confirming 10% as the optimal fly ash content in cement.(2)The optimum moisture content of RBSM gradually increases with the mass fraction of recycled brick aggregate, while the maximum dry density decreases accordingly.(3)During the early curing stage, the splitting strength of RBSM gradually decreases with increasing recycled brick aggregate mass fraction, while the unconfined compressive strength first increases and then decreases, peaking at a mass fraction of 50%. As the curing age increases, the mechanical strength of RBSM improves.(4)Through entropy-weighted TOPSIS theory, optimal mass fractions for cement and recycled brick aggregate were determined. The final recommended optimal mix design for recycled brick-based water-stabilized materials was 10% fly ash mass fraction in cement, 7% cement mass fraction in recycled brick-based water-stabilized material, and 50% recycled brick aggregate mass fraction in recycled brick aggregate.
