为丰富地质聚合物的制备原料,并拓宽污泥和煤矸石资源化利用途径,采用热活化污泥与煤矸石在碱性激发的条件下制备地质聚合物,借助X射线衍射、扫描电子显微镜和傅里叶红外光谱分析了地质聚合物试块的宏观、微观性能。结果表明:经900℃焙烧45 min的污泥(粒度

In order to enrich the preparation materials of geopalymer, and broaden the utilization way of sludge and coal gangue, the authors used thermally activat ed sludge and coal gangue to prepare the geopolymer under the condition of alkaline excitation.The XRD, SEM, FT-IR were used to analyse the geopolymerOs macrosc opic and microscopic properties.The results showed the compressive strength of the geopolymer could reach 39.8 MPa, prepared with 40% thermally activated sludge (
