人工沙中黏土含量优化试验研究

Research on Clay Content Optimization Experiment in Artificial Sand

摘要: 人工沙中黏土含量的多少是影响其应用范围的因素之一，基于黏土对亚甲蓝的吸附特性，常用亚甲蓝试验检测人工沙的黏土含量。分析了人工沙中黏土含量高的原因，通过试验，探讨了不同水洗次数对人工沙中黏土含量的影响。

Abstract: The clay content in artificial sand is one of the factors that affect its application range.Based on the clay adsorption feature to methylene blue，the clay content in artificial sand is usually tested by methylene blue.The reason of high clay content in artificial sand was analyzed，and the effect of different washing times on clay content in artificial sand was discussed.
