摘要
运用多试件重复测量设计的方差分析方法,并对原始数据分析采用Bonferroni法进行两两比较,测试碳化和氯盐双重腐蚀的试件强度,分析不同氯离子量和水灰比对不同龄期碳化后钢筋混凝土抗折强度和抗压强度的影响。结果表明:水灰比对混凝土试件强度影响显著;随着水灰比的增大,氯盐对混凝土试件的强度有一定的促进作用。
Using the variance analysis of multi-specimen repeated measurement design and the Bonferroni method, we tested the strength of reinforced concrete with carbonized and chloride double corrosion, and studied the effects of different chloride ion and water-cement ratio on the flexural strength and compressive strength of reinforced concrete with varied ages after carbonation. The water-cement ratio has a significant effect on the strength of concrete specimen. With the increase of wa- ter-cement ratio, the chloride salt could improve the strength of the reinforced concrete.
