影响兰州地区黄土比表面积的因素分析

he specific surface area of soil (SSA) is crucial for the interaction of ions and water molecules with the soil particles. Therefore, many physical and chemical properties of soil are determined by its total specific surface area. There are a number of specific surface area measurement. This paper describes two test procedures for determining the total surface area of loess using the Ethylene Glycol Monoethyl Ether (EGME) and Methylene blue (MB). Test results are presented demonstrating the effect of various test parameters on the results. Results for a number of different fine-grained soils are presented. A detailed recommended test procedure is given. The proposed method uses simple and inexpensive laboratory equipment, is relatively simple to perform, and allows for rapid determination of SSA.
