高强混凝土在冻融循环与硫酸铵侵蚀双因素作用下的交互分析

INTERACTIVE ANALYSIS OF HIGH STRENGTH CONCRETE SUBJECTED TO BOTH FREEZE-THAW CYCLES AND AMMONIUM SULPHATE SOLUTION

进行了高强混凝土在冻融循环与硫酸铵侵蚀的相关试验 ,得出高强混凝土在双因素作用下的一般破坏规律 ;通过方差分析手段定义了交互因子 ,定量地分析了双因素作用下各因素包括交互项的影响程度 ,从而对双因素作用下高强混凝土的劣化规律作了深层次的阐述。

The experiments of high strength concrete (HSC) subjected to freeze\|thaw cycles and ammonium sulfate corrosion have been carried out in this paper,and the normal damage rules of HSC under the action of such two factors have been provided.Furthermore,we quantitatively analyzed the influence of each factor including interactive term by defining interactive coefficient through two\|way analysis of variance.Based on these studies,the degenerate process of HSC affected by such two factors has been explained profoundly.
