做石灰edta试验最佳含水率越大石灰得质量越小。



如：    4%的掺灰土  最佳含水率16.4  

           6%的掺灰土  最佳含水率17.2



         做出得edta耗量为什么6%的比4%的大呢？





4%edta          石灰剂量                          edta耗量

                         2                                      7.2

                         3                                      9.7

                         4                                      11.6

                         5                                       13.3

                         6                                       15.4



6%                   石灰剂量                             edta耗量



                         3                                       12.1

                         4                                        13.3

                         5                                        14.2

                         6                                         15.5

                         7                                          16.6
