摘　　要：现行标准检测水泥石灰综合稳定土中剂量的方法只能检测出结合料的剂量,而无法区分水泥和石灰各自的剂量,不利于准确控制施工质量。通过试验详细分析了现行标准检测方法中存在的问题,并根据EDTA滴定反应原理及水泥与石灰在氯化铵溶液中钙溶出速率的不同,提出新的检测方法,对不同配比进行室内试验验证。结果表明:新的检测方法能够准确测得水泥石灰稳定土中的水泥剂量和石灰剂量。该方法可进一步推广应用于其他公路无机结合料稳定材料的水泥(石灰)剂量的测定。The current standard method for detecting the doses of cement and lime composite stabilized soil can only detect the binder dosage,but unable to distinguish the individual dose of cement and lime,which is not conducive to accurately control the construction quality.Through experiment,we analyzed the problems existing in the current standard testing methods,and according to the principle of EDTA titration reaction and cement and lime in ammonium chloride solution of calcium dissolution rate,we put forward a new detection method,and carried out indoor experiment on different proportion.The results show that the new test method can accurately measure the cement dose of cement lime stabilized soil and lime dose.This method can be further applied to other highway stable inorganic binder materials of cement(lime)dose determination.
