摘要
为了研究用NIPGA方法快速检测水泥中氯离子含量的可行性,本文设计了测量装置,并用MCNP程序模拟了不同氯离子含量的检测结果。模拟计算结果表明,氯离子含量小于0.10%时,测量值的绝对误差低于0.002%;氯离子含量在0.10%～1.0%时,测量值的绝对误差低于0.020%,达到了GB/T176-2008标准的要求,可见用NIPGA方法快速检测水泥中氯离子含量是可行的。
In order to study the possibility of fast analyzing the chloride ion content in cement by NIPGA method,the author of this paper designs the measuring equipment and simulates the measuring results of different chloride ion contents using the MCNP program.The simulating calculation results show that when chloride ion content is less than 0.10 %,the absolute error is less than 0.002%;when chloride ion content is during 0.10 %～1.0%,the absolute error is less than 0.020%,which meets the requirements of the standard GB/T176-2008.It＇s feasible to quickly measure the chloride ion content in cement by NIPGA method.
