Method for preparing ceramsite from gasified slag and prepared ceramsite
The invention provides a method for preparing ceramsite from gasified slag. Raw materials for preparing the ceramsite comprise the following components in parts by weight: 31-60 parts of a first component, 39-68 parts of a second component, 1-20 parts of a third component and 0.1-1 part of a fourth component, the first component is gasified slag with the water content of 50-70 wt% and the dry basis carbon content of 35-45 wt%; the second component is fly ash and/or engineering residue soil, in the second component, the total content of Al2O3 and SiO2 is larger than or equal to 60 wt%, and the content of Al2O3 is smaller than or equal to 25 wt%; the third component is bentonite and/or kaolin; and the fourth component is a plasticizer. According to the invention, the gasified slag with relatively high water content and specific dry basis carbon content is matched with the fly ash and/or the engineering muck, the bentonite and/or the kaolin and the plasticizer to prepare the ceramsite, and the prepared ceramsite is stable in bulk density, high in strength and low in water absorption rate.
本发明提供一种气化渣制备陶粒的方法，制备陶粒的原料按重量份包括以下组分：第一组分31‑60份，第二组分39‑68份，第三组分1‑20份，第四组分0.1‑1份；所述第一组分为含水率50‑70wt％、干基含碳量35‑45wt％的气化渣；所述第二组分为粉煤灰和/或工程渣土，在所述第二组分中，Al2O3和SiO2的总含量≥60wt％，并且Al2O3的含量≤25wt％；所述第三组分为膨润土和/或高岭土；所述第四组分为塑性剂。本发明采用具有较高含水率并具有特定的干基含碳量的气化渣，与粉煤灰和/或工程渣土、膨润土和/或高岭土以及塑性剂相互配合以制备陶粒，制得的陶粒堆积密度稳定、强度高、吸水率低。
