基于RSM的工业副产品改性硫铝酸钙水泥性能分析
Performance analysis of industrial by-products modified calcium sulphoaluminate cement based on RSM
摘要
Abstract
To investigate the pattern of influence of industrial by-products such as flue gas desulfuriza-tion gypsum(FGDG),fly ash(FA),and limestone(LS)on the strength and pH of calcium sul-phoaluminate cement(SAC),FGDG,FA and LS were used as solid waste admixture to modify SAC clinker and the modified SAC cured for 7 d and 28 d was tested for unconfined compressive strength(UCS)and pH.Response surface methods(RSM)were also used to develop regression models for the UCS and pH of the modified SAC.The effect patterns of each factor on UCS and pH were analyzed.The results of the study show that both the UCS and pH of the modified SAC are influenced by the sin-gle and multifactorial effects of FGDG,FA,and LS.The interaction between FGDG and LS,LS and FA has a significant effects on UCS7 d and UCS28 d.The interaction between LS and FA,FGDG and FA has a significant effects on pH7 d,but not on pH28 d.The RSM-BBD multi-objective optimization method are used to optimize industrial by-products,the established regression model has high reliability and accuracy,and the optimal addition ratio meeting the requirements of high strength and low alkali-nity is obtained,and the error of the test and the predicted values is small under this ratio.关键词
