Effect of Curing Temperature on Mechanical Properties of Sanitary Ware Porcelain based Geopolymer Mortar

The objective of this study was to investigate the effect curing temperature on mechanical properties sanitary ware porcelain powder-based geopolymer paste and mortar under various temperatures. setting time, porosity, water absorption, compressive strength specimens mixed with alkaline concentrations 8M, 10M, 12M, 14M were compared. All cube (50×50×50 mm) placed into drying ovens for 24 hours at 60°C, 75°C, 90°C, 105°C, respectively. then air-cured 1, 3, 7, 14, 28 days. results showed that elevated accelerated polymerization process geopolymerization reaction. time varied between 89 mins 380 mins. It variability depending concentration initial temperature. pastes decreased when increased. An increasing in oven final times. Similar this, rate absorption permeability porcelain-based temperatures increments concentration. lowest porosity specimen 2.1% 15.7%, increased as highest day found 105°C ultimate 64.45 N/mm2. Scanning electron microscopy (SEM) X-ray diffraction (XRD) investigated microstructural geopolymers. Doi: 10.28991/CEJ-2023-09-08-01 Full Text: PDF
