冬施商品混凝土强度增长规律探索研究

Research on increasing rules of commercial concrete strength in winter construction

通过掺入不同数量粉煤灰,研究了在各种情况下冬施商品混凝土强度的增长规律,并通过对混凝土回弹法定性检测和钻芯法定量检测的对比,对各种数据进行了验证,总结了二者之间规律,为无损准确推算实体混凝土强度奠定了基础。

By mixing with different mount of fly ash,the paper researches the increasing rules for the strength of the commercial concrete in various situations,and proves all kinds of data by comparing with the springback test and core drilling method test,and sums up the rule between them,so as to lay the basement for calculating the undamaged concrete strength accurately.
