摘    要:采用高频红外碳硫仪快速测定混凝土中的硫含量.通过试验确定了适宜的分析条件:以水泥标准物质校正仪器,以铁屑、钨粒加锡粒为助熔剂,称样量为0.03~0.2g.用该法对4种混凝土样品进行测定,测定结果与化学法测定结果相吻合,5次测定结果的相对标准偏差不大于4%,精密度较为理想.

关 键 词:高频燃烧红外分析法  混凝土  硫含量

Abstract:The sulfur content in concrete was determined quickly by high-frequency combustion infrared absorption method.The proper test conditions were confirmed,which were as follows: the high frequency combustion infrared analyzer was calibrated by cement standard substance,the blended iron shavings,tungsten pellets,tin granules were used as flux,the weight of sample was 0.03-0.2 g.The results from four concrete samples demonstrated that the results detected by this method were accord with those by chemical method....
Keywords:high-frequency combustion infrared absorption method  concrete  content of sulfur
