AI Technical Summary
Existing technologies make it difficult to manufacture cost-competitive and consistent quality fly ash-containing products on an industrial scale, especially when manufacturing ceramic products. The fine powder and heavy metal content of fly ash makes its disposal difficult, and the solidification process of traditional methods is time-consuming. Time-consuming and high energy consumption.
Using a powder composition containing fly ash and plasticizer, through uniform mixing and adding an appropriate amount of water, a green product with sufficient wet strength is formed, and is sintered under low water content and appropriate pressure, using superplasticizer and Ceramic additives optimize particle size and rheological properties, reduce carbon content and water absorption, and increase sintered density and strength.
It achieves the manufacturing of high-quality ceramic products under conditions of low water content and low energy consumption, shortens the curing time and reduces the cost. The products have good wet strength and sintering density and are suitable for industrial production.
