Abstract

The sustainable management of Ceramic Tile Filter Press Cake Powder (FPW) and Pottery Shard Waste Powder (PW) is crucial to reducing environmental harm in the ceramics sector. These ceramic byproducts offer a valuable source of aluminosilicate powders, which can be used in the synthesis of geopolymer mortars as an innovative alternative to traditional raw materials. This study focuses on repurposing these materials as binders in geopolymer mortars and evaluating their performance after exposure to elevated temperatures. Geopolymers were formulated with varying FPW/PW ratios (100/0, 75/25, 50/50, 25/75, 0/100) and cured thermally at 90°C for either 6 or 24 h. Strength tests were conducted on mortars before and after heating at 400, 600, and 800°C. Selected samples underwent crystal structure (XRD) and microstructural (SEM/EDX) analyses both before and after thermal exposure. The results indicated that 24-hour cured geopolymers exhibited better initial strength, while the 6-hour cured mortars demonstrated superior residual strength post-heating. Geopolymers with higher FPW content displayed greater thermal resistance than those with higher PW content. Overall, ceramic waste proved to be a viable alternative material for producing geopolymers, offering an effective solution for waste reduction in the ceramics industry.

期刊介绍： The aim of Advanced Powder Technology is to meet the demand for an international journal that integrates all aspects of science and technology research on powder and particulate materials. The journal fulfills this purpose by publishing original research papers, rapid communications, reviews, and translated articles by prominent researchers worldwide. The editorial work of Advanced Powder Technology, which was founded as the International Journal of the Society of Powder Technology, Japan, is now shared by distinguished board members, who operate in a unique framework designed to respond to the increasing global demand for articles on not only powder and particles, but also on various materials produced from them. Advanced Powder Technology covers various areas, but a discussion of powder and particles is required in articles. Topics include: Production of powder and particulate materials in gases and liquids(nanoparticles, fine ceramics, pharmaceuticals, novel functional materials, etc.); Aerosol and colloidal processing; Powder and particle characterization; Dynamics and phenomena; Calculation and simulation (CFD, DEM, Monte Carlo method, population balance, etc.); Measurement and control of powder processes; Particle modification; Comminution; Powder handling and operations (storage, transport, granulation, separation, fluidization, etc.)
