Decay Model of Effective Calcium and Magnesium Content in Lime-stabilized Waste Slurry |
| |
| Abstract: | Through EDTA titration test, the mathematical model of effective calcium and magnesium content under different curing conditions and compaction state is established. The attenuation law of effect calcium and magnesium content in the lime stabilized waste slurry applied to road engineering is analyzed and studied. The results of the research show that there is a linear relationship between the effective calcium and magnesium content of lime stabilized waste slurry and lime dosage, and the attenuation model of effective calcium and magnesium content is related to curing conditions and compaction state. Through the comparison of model data and experimental data, it is found that the established attenuation model of effective calcium and magnesium content has a certain prediction accuracy. |
