| 成果简介 | NOVELTY - Composition comprises manufactured sand (m-sand); sodium silicate (Na2SiO3); sodium hydroxide (NaOH); coal washery rejects, where the coal washery rejects are processed into fine particles suitable for use as fine aggregate and additional additives. USE - Composition for producing artificial fine aggregates using coal washery rejects for concrete production. ADVANTAGE - The composition is prepared by repurposing industrial waste. The artificial fine aggregates have high-strength, and is environmentally friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing artificial fine aggregates from coal washery rejects, which involves: i. sourcing coal washery rejects from the coal washing process; ii. cleaning and removing contaminants from the coal washery rejects; iii. grinding the coal washery rejects into fine particles; iv. mixing the fine coal washery rejects with sodium silicate and sodium hydroxide to form an alkaline activator solution prepared using sodium hydroxide with sodium silicate in a weight ratio of 2.0 to 2.5:1; v. allowing the mixture to undergo geopolymerization reaction, resulting in a hardened matrix that binds the fine aggregate. |
