High-strength ceramsite fired by using coal-fired solid waste and preparation method of high-strength ceramsite
The invention discloses a high-strength ceramsite fired by using coal-fired solid waste and a preparation method thereof, and solves the problem that the strength of ceramsite fired by using coal-fired solid waste in the prior art is difficult to reach the national index for high-strength ceramsite. The technical problem that fly ash, slag and pebble coal are difficult to bond into balls in the firing process of the ceramsite is solved. The invention relates to high-strength ceramsite fired from coal-fired solid waste and a preparation method. The high-strength ceramsite comprises 70-80% of fly ash, 10-15% of slag powder, 5-20% of pebble coal powder and 1-3% of a Na2SiO3 aqueous solution. The high-strength ceramsite prepared by the preparation method disclosed by the invention reaches related indexes for light aggregates in GBT17431.1-2010 Lightweight Aggregate and Experimental Methods thereof, the preparation method of the high-strength ceramsite is simple, the energy consumption is low, the material consumption is low, the problems of stockpiling treatment and comprehensive utilization of a large amount of solid wastes in a coal-fired power plant are effectively solved, and the high-strength ceramsite is environment-friendly and has a wide application prospect. The method has great economic value and is suitable for industrial popularization.
本发明公开了一种利用燃煤固体废弃物烧制的高强陶粒及制备方法，解决了现有技术中利用燃煤固体废弃物烧制成的陶粒强度难以到达国家对于高强度陶粒的指标，在陶粒的烧制过程中粉煤灰、炉渣与石子煤难以较好的粘结成球的技术问题。它包括利用燃煤固体废弃物烧制的高强陶粒及制备方式，所述高强度陶粒包括：70‑80%粉煤灰、10‑15%炉渣粉、5‑20%石子煤粉，1‑3%Na2SiO3水溶液。本发明制备所得的高强度陶粒达到了GBT17431.1‑2010《轻集料及其实验方法》中对轻集料的相关指标，且高强度陶粒的制备方式简单、能耗低且物耗少，有效地解决了燃煤电厂大量固体废弃物堆存处理和综合利用的问题，对于环境友好，具有较大的经济价值，适于工业化推广。
