中文摘要：以高钙粉煤灰为主合成材料,掺入印染污泥,并以水玻璃和氢氧化钠为激发剂,制备地质聚合物材料,并借助标准维卡仪、万能试验机、FTIR、SEM、EDS和ICP-MS等手段,分析印染污泥对该地质聚合物材料性能的影响。结果表明:粉煤灰地质聚合物的凝结时间随着印染污泥掺量增加而缩短,在掺量高于20%时,由于凝结时间太短而不利于成型;其强度在掺量为10%左右时略有提高,而当掺量大于20%时,强度极大地下降;对掺量20%的试样进行重金属浸出含量测试发现,该地质聚合物具有很好的封固重金属的性能,试样重金属浸出含量远低于限量的要求。

外文摘要：This paper aims to prepare a new geopolymer material using high calcium fly ash and dyeing sludge as raw materials, and water glass and sodium hydroxide as activator. By means of standard Vicat apparatus, universal testing machine, FTIR, SEM, EDS and ICP-MS, analysis of the effect of dyeing sludge on properties of the geopolymer material was taken out. The results indicated that the setting time of the fly ash geopolymer shortened with the increase of the admixture of dyeing sludge. When its mass ratio was higher than 20%, the setting time is too short and not conducive to sample preparation. The compressive strength increased when dyeing sludge content was about 10wt%, while dropped remarkably when greater than 20wt%. Heavy metal leaching test of samples with 20wt% of dyeing sludge showed that the geopolymer had good sealing performance of heavy metals and the leaching concentration of heavy metals was far below limits.
