In order to explore the feasibility of using waste concrete to dispose expansive soil and make it as roadbed filler, the waste concrete and expansive soil were mixed evenly according to the ratio of 96 : 4, 92 : 8, 88 : 12, 84 : 16, 80 : 20 and 76 : 24. The boundary moisture content, linear shrinkage rate, expansion force and compaction tests were carried out. The influence of curing time was considered in unconfined strength and CBR tests to explore the improvement effect of the selected materials. The experimental results show that the liquid limit and plastic index decrease first and then increase with the increase of waste concrete content, and the minimum value appears when the content is 12 %, while the plastic limit increases slowly. The linear shrinkage rate increases first and then decreases with the increase of dosage, and the linear shrinkage rate is the smallest when the dosage is 12 %. The expansion force under different curing periods decreases slowly with the incorporation of concrete. When the dosage is 12 %, the dry density of the treated expansive soil is greater than that of the plain soil, and the optimum moisture content is less than that of the plain soil. Considering various factors, 12 % is determined as the best dosage. Under this dosage, the unconfined compressive strength of the mixed soil can reach the peak value, and the bearing capacity of the treated soil is about 5 times that of the plain soil. The treated expansive soil can be used as roadbed filler.

为探究废弃混凝土处置膨胀土使之作为路基填料的可行性,按照96∶4、92∶8、88∶12、84∶16、80∶20、76∶24比例将废弃混凝土与膨胀土混合均匀后制样,进行界限含水率、线性收缩率、膨胀力和击实试验,并在无侧限强度和CBR试验中考虑养护时间的影响,以探究所选材料的改良效果。试验结果表明,液限和塑性指数随废弃混凝土掺量增大呈先降后升的趋势,在掺量为12%时出现最小值,塑限则缓慢上升;线性收缩率随掺量增加先增后减,掺量在12%时线性收缩率最小;不同养护期的膨胀力均随混凝土的掺入量缓慢下降;且在掺量为12%时,处置后的膨胀土干密度大于素土,最佳含水率小于素土。综合考虑各因素,确定掺量12%为最佳掺量,在该掺量下制样养护(足够时间后)混合土的无侧限抗压强度可达到峰值,且此时处置土承载力约为素土的5倍,处置后的膨胀土可作为路基填料。

为探究废弃混凝土处置膨胀土使之作为路基填料的可行性,按照96∶4、92∶8、88∶12、84∶16、80∶20、76∶24比例将废弃混凝土与膨胀土混合均匀后制样,进行界限含水率、线性收缩率、膨胀力和击实试验,并在无侧限强度和CBR试验中考虑养护时间的影响,以探究所选材料的改良效果。试验结果表明,液限和塑性指数随废弃混凝土掺量增大呈先降后升的趋势,在掺量为12%时出现最小值,塑限则缓慢上升;线性收缩率随掺量增加先增后减,掺量在12%时线性收缩率最小;不同养护期的膨胀力均随混凝土的掺入量缓慢下降;且在掺量为12%时,处置后的膨胀土干密度大于素土,最佳含水率小于素土。综合考虑各因素,确定掺量12%为最佳掺量,在该掺量下制样养护(足够时间后)混合土的无侧限抗压强度可达到峰值,且此时处置土承载力约为素土的5倍,处置后的膨胀土可作为路基填料。

In order to explore the feasibility of using waste concrete to dispose expansive soil and make it as roadbed filler, the waste concrete and expansive soil were mixed evenly according to the ratio of 96 : 4, 92 : 8, 88 : 12, 84 : 16, 80 : 20 and 76 : 24. The boundary moisture content, linear shrinkage rate, expansion force and compaction tests were carried out. The influence of curing time was considered in unconfined strength and CBR tests to explore the improvement effect of the selected materials. The experimental results show that the liquid limit and plastic index decrease first and then increase with the increase of waste concrete content, and the minimum value appears when the content is 12 %, while the plastic limit increases slowly. The linear shrinkage rate increases first and then decreases with the increase of dosage, and the linear shrinkage rate is the smallest when the dosage is 12 %. The expansion force under different curing periods decreases slowly with the incorporation of concrete. When the dosage is 12 %, the dry density of the treated expansive soil is greater than that of the plain soil, and the optimum moisture content is less than that of the plain soil. Considering various factors, 12 % is determined as the best dosage. Under this dosage, the unconfined compressive strength of the mixed soil can reach the peak value, and the bearing capacity of the treated soil is about 5 times that of the plain soil. The treated expansive soil can be used as roadbed filler.
