Coal gasification slag unfired ceramsite and preparation method thereof
The invention belongs to the technical field of ceramsite preparation, and provides coal gasification slag unfired ceramsite and a preparation method thereof. The raw materials of the coal gasification slag unfired ceramsite comprise a coal gasification slag unfired ceramsite matrix, a binding agent, an alkali activator, a water reducing agent and water, wherein the coal gasification slag unfired ceramsite matrix is prepared from the following components in percentage by mass: 50-60% of coal gasification slag, 15-30% of fly ash, 5-15% of river sand and 15-20% of cement; the use amounts of the binding agent and the alkali activator are 7-10% and 0-3% of the mass of the coal gasification slag unfired ceramsite matrix respectively. By utilizing the characteristics of low apparent density and pozzolanic activity of the coal gasification slag raw material, the invention aims to prepare the unfired ceramsite with low volume density, low water absorption rate and high strength by adjusting the raw material ratio and the quantity of the alkali activator without adding a pore-forming agent and without surface treatment on the basis of ensuring that the mixing amount of the coal gasification slag is greater than or equal to 50% and the mixing amount of the cement is less than or equal to 20%.
本发明属于陶粒制备技术领域，提供了一种煤气化渣免烧陶粒及其制备方法。煤气化渣免烧陶粒的原料为煤气化渣免烧陶粒基体、结合剂、碱激发剂、减水剂和水，煤气化渣免烧陶粒基体由以下质量百分比的组分制成：煤气化渣50‑60％、粉煤灰15‑30％、河沙5‑15％、水泥15‑20％；结合剂和碱激发剂的用量分别为煤气化渣免烧陶粒基体质量的7‑10％和0‑3％。本发明利用煤气化渣原料表观密度低、有火山灰活性的特性，旨在保证煤气化渣掺量≥50％、水泥掺量≤20％的基础上，通过调节原料配比和碱激发剂数量，不需添加造孔剂，不需表面处理，制备出低体积密度、低吸水率、高强度的免烧陶粒。
