对一系列配合比的固化剂稳定铁尾矿砂进行7d无侧限抗压强度测试,选取若干能够满足强度要求的配和比进行进一步力学性能试验研究,探讨分析结合料掺量、养生龄期等因素对混合料力学性能的影响。试验结果表明:固化剂稳定铁尾矿砂具有良好力学性能,能够作为高速公路底基层材料使用。
A series of compounding agent stabilized iron tailings were tested for unconfined compressive strength for 7 days. Several mechanical properties tests were conducted with the blending ratio that can meet the strength requirements. Effect of Factors on Mechanical Properties of Mixture. The experimental results show that the hardener stabilized iron tailing sand has good mechanical properties and can be used as the base material of expressway.
