Split tensile strength of slag-based boroaluminosilicate geopolymer

Split tensile strength of slag-based boroaluminosilicate geopolymer In this study, split tensile strength of the slag-based boroaluminosilicate geopolymers was studied. The metallurgical slag obtained from the rockwool furnace was used as the aluminosilicate source. The mixture of sodium hydroxide and borax was used as the alkali activator. The experiments were designed using the Taguchi method. The four main factors that considered in four different levels are sodium hydroxide concentration, curing time, the weight ratio of the borax to sodium hydroxide solution, and the weight ratio of the alkali activator to slag. In total, 16 set of tests based on the L9 array was conducted. The ANOVA analysis results showed that the specimen with the curing time of 14 days, sodium hydroxide concentration of 8 M, the weight ratio of the borax to sodium hydroxide solution of 0.9, and the weight ratio of the alkali activator to slag of 0.7 possesses the highest strength of 8.48 ± 1.07 MPa. Also, the FT-IR results revealed that, the slag-based boroaluminosilicate geopolymer sample with the highest strength had a B–O bond; however, for the slag-based boroaluminosilicate geopolymer sample with the lowest strength, no B–O bond was detected. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of the Australian Ceramic Society Springer Journals

Abstract

In this study, split tensile strength of the slag-based boroaluminosilicate geopolymers was studied. The metallurgical slag obtained from the rockwool furnace was used as the aluminosilicate source. The mixture of sodium hydroxide and borax was used as the alkali activator. The experiments were designed using the Taguchi method. The four main factors that considered in four different levels are sodium hydroxide concentration, curing time, the weight ratio of the borax to sodium hydroxide solution, and the weight ratio of the alkali activator to slag. In total, 16 set of tests based on the L9 array was conducted. The ANOVA analysis results showed that the specimen with the curing time of 14 days, sodium hydroxide concentration of 8 M, the weight ratio of the borax to sodium hydroxide solution of 0.9, and the weight ratio of the alkali activator to slag of 0.7 possesses the highest strength of 8.48 ± 1.07 MPa. Also, the FT-IR results revealed that, the slag-based boroaluminosilicate geopolymer sample with the highest strength had a B–O bond; however, for the slag-based boroaluminosilicate geopolymer sample with the lowest strength, no B–O bond was detected.
