High-performance sludge inorganic artificial stone and preparation method thereof
The invention discloses a high-performance sludge inorganic artificial stone and a preparation method thereof. The preparation method comprises the following steps: (1) sieving wet sludge to remove impurities; (2) carrying out aging treatment on the sludge; (3) dehydrating and drying the sludge; (4) crushing the sludge to obtain sludge powder; (5) calcining the sludge in a muffle furnace at the temperature of 1200 DEG C to obtain calcined sludge with certain activity; and (6) adding steel slag, an exciting agent and other materials into the calcined sludge powder to prepare the sludge inorganic artificial stone. The inorganic artificial stone prepared from the waste river sludge has the remarkable characteristics of stable performance, low cost, low carbon, environment friendliness and the like; meanwhile, the sludge is subjected to high-temperature calcination thermal excitation and alkali excitation composite treatment, so that the activity of the sludge is greatly excited, and the performance of the sludge inorganic artificial stone can be effectively improved.
本发明公开了一种高性能淤泥无机人造石及其制备方法，该制备方法包括以下步骤：(1)将湿润的淤泥过筛去除杂质；(2)对淤泥陈化处理；(3)将淤泥进行脱水干燥；(4)对淤泥进行粉碎处理得到淤泥粉料；(5)将淤泥放入1200℃的马弗炉中煅烧得到煅烧后的具有一定活性的淤泥；(6)在煅烧后的淤泥粉料中添加钢渣、激发剂等材料制备淤泥无机人造石。本发明利用废弃的河道淤泥制得的无机人造石具有性能稳定、成本低、低碳环保等显著特点；同时对淤泥进行高温煅烧热激发及碱激发复合处理，极大地激发了淤泥的活性，能有效地提升了淤泥无机人造石性能。
