灰色理论预测锂渣高性能混凝土中锂渣的临界细度

摘要

采用灰色理论建立GM(1,1)模型来预测锂渣高性能混凝土中锂渣的细度,结果表明:通过GM(1,1)模型预测出的锂渣细度与试验值吻合较好；并通过残差检验,相对误差均≤3％.比较GM(1,1)模型计算值与试验值,证明这种灰色理论预测方法是简便易行的、可靠的、准确的,可以进一步探究应用于高性能混凝土其它性能的试验研究中.%Using grey theory and establishing GM( 1,1) Model to predict fineness of lithium slag in the high performance concrete with lith ium slag. The results shows, that lithium slag's fineness through the GM (1,1) model of the prediction tallywell with experimental results. And through the residual inspection,all the relative error are within 3%. Therefore,it prones that the Grey theory prediction method is easy and conven ient , reliable and accurate. It can further explore other properties in the experimental research of the high performance concrete within lithium slag.
