本文介绍了混凝土泌水简易预测模型的试验结果。试验中改变水灰比、单位含水量和外加剂种类。实验结果表明，对于泌水的预测，只需要建立一个常系数即可。素混凝土和掺引气剂的混凝土中，该系数值趋于一致。而掺引气减水剂的混凝土比素混凝土稍大。即使品牌或地区相同，由于使用的材料很多，系数也有很大差异。
This paper presents the results of experiment on the simple prediction model of bleeding of concrete. In the experiment, water cement ratio, unit water content and the kind of chemical admixture were varied. At the result of experiment, for the prediction of bleeding, only one constant coefficient need to be established. The value of this coefficient became the similar one in the plain concrete and the concrete with air-entraining agent. But that of concrete with air-entraining and water-reducing agent was a little bit larger than that of plain concrete. And the coefficient varied largely due to the lots of used material even if the brand or district was the same.
