对不同水泥量混凝土抗冻融实验的统计学分析

The statistical analysis of the different amount of cement concrete anti-freeze-thaw test

通过对混凝土冻融循环检测数据进行统计分析,大多数样本经冻融循环后,水泥量的增加与重量损失率、相对动弹性模量变化呈不相关或相关程度不大,据此提出宜在保障施工质量的前提下,选用合适的外加剂,适当减少水泥用量,从统计学角度,为宏观判定普通混凝土抗冻能力提供了参考。

The test indicates most of the samples after freeze--thaw cycle, an increase of cement volume and weight loss rate, the relative dynamic elastic modulus changes were not related or not related to the extent, through the statistical analysis of the freeze--thaw cycle of concrete test data. For protecting the quality of construction, a suitable additive should be chosen; the amount of cement should reduce. From the statistical point of view, it provides the reference for the macro--determinant concrete antifreeze.
