摘要
测定混凝土外加剂中的碱含量时,对试样进行灼烧预处理或采用标准加入法进行测定,可消除试样的基体影响,同时也可以避免一般的试样处理过程中的试剂空白以及操作过程中试液的污染与损失可能造成的结果波动。提出的碱含量测定操作步骤具有操作简便、速度快、分析结果精密度好和准确度高的特点。
When admixture are the alkali contents in the concrete determined determined by the pre - and the ignition or samples are the standard addition method, the disadvantages from the matrix can be eliminated and the possible fluctuating results from the reagent shortage in treating the common samples or the contamination and loss of the test liquid in operation can be avoided. The operating steps given in this paper for determining the alkali content have the characteristics of easy operation, fast speed, and excellent analytic precision and nicety.
