【摘要】：介绍了新拌混凝土浮浆层厚度和硬化混凝土浮浆率这2种表征浮浆严重程度的测试方法。结果表明,2种测试方法均能够在一定程度上有效地对混凝土的浮浆情况进行表征。新拌混凝土浮浆层厚度测试方法具有测试快捷、试验周期短、可以快速得出结论的优点,但无法区分水泥浮浆和对实际工程危害更大的粉煤灰浮浆;而硬化混凝土浮浆率测试方法的优点在于其测试的是硬化后强度较低的有害浮浆部分,其值对于实际工程应用可能更具指导意义,但试验周期相对较长。
[Abstract]:This paper introduces two kinds of measuring methods, namely, the thickness of fresh concrete floatation slurry layer and the floatation rate of hardened concrete. The results show that both methods can effectively characterize the floating slurry of concrete to some extent. The method of measuring the thickness of fresh concrete floating slurry layer has the advantages of quick test, short test period and quick conclusion, but it can not distinguish cement floating slurry from fly ash floatation slurry which is more harmful to practical engineering. The advantage of the method is that it is the harmful part of concrete with low strength after hardening, and its value may be more instructive for practical engineering application, but the test period is relatively long.
