抗硫酸盐水泥混凝土的合理试件尺寸选取

Choice of the reasonable specimen size of anti-sulfatefor concrete

采用两种不同尺寸的混凝土试件进行室内混凝土抗硫酸盐腐蚀性快速破坏试验,寻求适用于室内混凝土抗硫酸盐腐蚀性快速破坏试验的最合理的混凝土试件尺寸。结果表明:采用尺寸为100mm×100mm×400mm的混凝土试件比采用尺寸为40mm×40mm×160mm的混凝土试件进行抗硫酸盐腐蚀性快速破坏试验的试验结果具有较好的准确性,所以进行混凝土抗硫酸盐腐蚀性室内快速破坏试验时选取100mm×100mm×400mm的试件尺寸较为合理。

This paper describes a study taking the rapid destruction anti-sulfate erosion indoor test on the concrete with different size specimen,to get the most reasonable concrete samples size,which apply to the anti-sulfate erosion damage fast test.The test results show that： the 100mm×100mm×400mm size specimen of the concrete has good accuracy than the 40mm×40mm×160mm size specimen of the concrete in the anti-sulfate erosion damage fast test,so concrete of sulfate corrosive indoor rapid destruction test select 100mm×100mm×400mm size of test is more reasonable.
