This paper aims to study the synthesized geopolymers by using Ground Sediment (GS)and Calcium Carbide Residue (CCR) as aluminosilicate sources. The efficiency of the source materials in producing geopolymer products was optimized by using Taguchi method via five parameters including Sodium Hydroxide (NaOH) concentration, Solid to Liquid ratio, Sodium Silicate to Sodium Hydroxide (Na₂SiOɜ/NaOH) ratio, oven curing time and oven curing temperature. Each of the parameter was tested at four levels with L16 array. The performance of the specimens was assessed by density test and compression test. Taguchi analysis of the experimental result suggested a specimen with NaOH concentration of 8M, Solid to Liquid Ratio equals to 1, Na₂SiOɜ/NaOH of 2, oven curing time for 36 hours and oven curing temperature at 60°C to acquire the highest strength after 14 days of curing at room temperature.

Abstract

This paper aims to study the synthesized geopolymers by using Ground Sediment (GS)and Calcium Carbide Residue (CCR) as aluminosilicate sources. The efficiency of the source materials in producing geopolymer products was optimized by using Taguchi method via five parameters including Sodium Hydroxide (NaOH) concentration, Solid to Liquid ratio, Sodium Silicate to Sodium Hydroxide (Na₂SiOɜ/NaOH) ratio, oven curing time and oven curing temperature. Each of the parameter was tested at four levels with L16 array. The performance of the specimens was assessed by density test and compression test. Taguchi analysis of the experimental result suggested a specimen with NaOH concentration of 8M, Solid to Liquid Ratio equals to 1, Na₂SiOɜ/NaOH of 2, oven curing time for 36 hours and oven curing temperature at 60°C to acquire the highest strength after 14 days of curing at room temperature.
