Paper Title:
Experimental Research of Self-Igniting Coal Gangue Bonding Material by Orthogonal Design
  Abstract

the self-igniting coal gangue in Gaode Mine, Fuxin city of Liaoning Province by physical and chemical method.first,orthogonal test was applied to study the influence of the fineness of coal gangue on strength of the bonding material;then on the basic of it,use this method again to clarify the effects of self-igniting coal gangue's addition on th strength of bonding material.The results of this experiment showed that self-igniting coal gangue can be used as cement’s active admixture .range analysis and variance analysis indicated that the amount of coal gangue had significant influence on binding material’s strength ,and it will make the material have outstanding performance when proportion reaches to 25%~35% of material sum, at the premise that the variety and the content of activator is suitable.The study on self-igniting coal gangue cement could not only widen the application area of coal gangue and the variety of cement ,but also solve the problem of environmental pollution caused by the great quantity of coal gangue.According with building materials industry's developing concept about saving energy,reduceing pollution,protecting the environment, green environmental protection etc in 21st century .
