摘要
针对EDTA滴定法测得的灰剂量与实际的掺灰量存在较大偏差的问题,该文通过室内试验,研究了不同塑性指数、压实状态、养护温度等因素对灰剂量衰减的影响。结果表明:随塑性指数的增加,灰剂量衰减率减小;灰剂量衰减率随养护温度增加呈线性增大;压实度越大,灰剂量衰减越快。
Accoding to the problem that the measured lime content through EDTA test is different with actual lime content, the influence factors of lime content regularity are studied,including plasticity index,compaetness and euring temperature. The results show that lime content reduction rate reduces with plasticity index increasing, the faster the compactness declines,the bigger the line content reduces.
