| 摘 要： | 利用城市污泥制备烧结砖,研究了污泥掺量和烧结温度对烧结砖性能的影响。结果表明:随着污泥掺量的增加,烧结砖的抗压强度逐渐降低;15%污泥掺量的试块抗压强度符合GB26538-2011储结保温砖和保温砌対要求;不同的烧结温度,烧结砖内部的物相组成也不相同,温度越高,玻璃相越多;污泥掺量的增加会改变试块的内部结构,气孔变多,晶体的不均匀性增大,最终导致试块的吸水率增大,导致污泥烧结砖试件的物理力学性能和耐久性变差。

| Abstract: | The effect of sludge dosage and sintering temperature on the properties of sintered bricks was studied by using municipal sludge to prepare sintered bricks. The results showed that the strength of sintered brick was significantly affected by the increase of sludge content. The strength of the test block with 15% sludge content meets the requirements of GB 26538--2011 "sintered insulating brick and insulating block". Different sintering temperature, sintered brick internal phase composition is not the same, the higher the temperature, the more glass phase. The increase of sludge content will change the internal structure of the test block,with more pores, the greater the connection between pores,the greater the heterogeneity of acnrydstals ultimately lead to the greater the water absorption rate of the test block. so that the physical properties and durability of the test block become worse. |
