Lightweight high-strength ceramsite prepared from aluminum ash and preparation method thereof
The invention provides lightweight high-strength ceramsite prepared from aluminum ash and a preparation method of the lightweight high-strength ceramsite, and belongs to the technical field of solid waste recycling. The method for preparing the lightweight high-strength ceramsite by using the aluminum ash comprises the following steps: mixing 60-86% of the aluminum ash, 5-20% of gasified slag, 5-20% of ferrosilicon ash, 4-10% of bentonite and an additive to obtain a mixed material; the mass of the additive is 2-4% of the total mass of the aluminum ash, the gasification slag, the ferrosilicon ash and the bentonite; adding water into the mixed material, and then sequentially balling, aging and drying to obtain ceramsite to be sintered; the ceramsite to be sintered is heated to 200 DEG C from the room temperature in 1-2 h, then heated to 500 DEG C from 200 DEG C in 1-2 h, then heated to 800 DEG C from 500 DEG C in 2-3 h, then heated to 1100 DEG C from 800 DEG C in 2-3 h and finally sintered at the temperature of 1100-1240 DEG C, and the light high-strength ceramsite is obtained.
本发明提供了一种利用铝灰制备的轻质高强陶粒及其制备方法，属于固废再利用技术领域。本发明利用铝灰制备轻质高强陶粒的方法，包括以下步骤：将铝灰60～86％、气化渣5～20％、硅铁灰5～20％、膨润土4～10％和外加助剂混合，得到混合物料；外加助剂的质量为铝灰、气化渣、硅铁灰和膨润土总质量的2～4％；向混合物料中加入水，然后依次进行成球、陈腐和干燥，得到待烧陶粒；将所述待烧陶粒先在1～2h内从室温升温至200℃，然后在1～2h内从200℃升温至500℃，接着在2～3h内从500℃升温至800℃，再在2～3h内从800℃升温至1100℃，最后在1100～1240℃的温度下进行烧成，得到轻质高强陶粒。
