改性污泥制备泡沫混凝土的可行性研究
Feasibility study on foam concrete prepared by modification sludge
摘要
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.关键词
