某高铝型铁尾矿低碳免烧砖的制备及性能研究OA
Preparation and performance research of low-carbon and non-fired brick with a high alumina iron tailings
为了解决铁尾矿堆存带来的环境压力,实现资源综合利用,以河北省张家口市某高铝型铁尾矿和水泥为原材料,通过压制成型的方式制备了一种低碳免烧砖.测量了铁尾矿免烧砖的抗压、抗折强度及密度,探究了水泥掺量和铁尾矿颗粒级配对该免烧砖性能的影响,并通过X射线衍射分析(XRD)、傅里叶红外光谱(FTIR)以及扫描电子显微镜(SEM)等手段探究了铁尾矿免烧砖的微观机理,结果表明:铁尾矿免烧砖的强度随着水泥掺量的增加而增大,铁尾矿颗粒级配会对铁尾矿免烧砖的强度产生显…查看全部>>
In order to solve the environmental pressure caused by the storage of iron tailings and achieve comprehen-sive resource utilization,a low-carbon unburned brick was prepared by pressing and molding a high alumina iron tailings and cement from Zhangjiakou city,Hebei province as raw materials.The compressive strength,flexural strength,and density of iron tailings unburned bricks were measured,and the effects of cement content and iron tailings particle size dis…查看全部>>
