| 摘 要： | 由于污泥在建材利用安全性方面存在较多质疑，致使污泥的建材利用一直得不到广泛推广。鉴于此，本实验对剩余污泥进行了改性处理，对改性后获得的泥渣与污泥蛋白液的特性进行了分析，同时对不同泥渣与泡沫掺量下的泡沫混凝土强度和耐火特性进行了研究。结果表明，改性污泥制备泡沫混凝土不存在安全隐患，获得的污泥蛋白发泡剂具有良好的发泡性能。制备的泡沫混凝土具有良好抗压强度、抗折强度，满足行业标准；同时泡沫混凝土的干密度、抗压强度及抗折强度都随着泡沫量的增加而降低；随着污泥渣的增加，泡沫混凝土的干密度和抗折强度下降，抗压强度则呈现先增加而后降低的趋势，在污泥渣质量分数为4%时，抗压强度最佳。耐火试验显示泡沫混凝土具有良好的耐火性能。因此，应用改性污泥制备泡沫混凝土具有较强的可行性。

| Abstract: | The utilization of sludge in building materials have not been widely used because of safety dispute. In this paper,modification treatment of excess sludge was carried out,and characteristics of dislodged sludge and sludge protein solution after modification treatment,and the influence of dislodged sludge and sludge protein solution with different contents on strength and fire-resistant performance of foam concrete were investigated. The results showed that foam concrete prepared by modification sludge has no potential safety risks,and the sludge protein solution had excellent foaming property. The prepared foam concrete had good compressive strength and breaking strength,which met the requirement of the industrial standard. Dry density,compressive strength and breaking strength decreased with the increase of foam quantity. As sludge mud increased,dry density and breaking strength decreased. Compressive strength first increased and then decreased. When the ratio of sludge mud was 4%(wt),compressive strength was optimum. Fire test showed that foam concrete has good fire-resistant performance. Therefore,foam concrete prepared by modification sludge had comparatively more feasible and reasonable. |
