Evaluation of chloride resistance of silica fume and glass waste MWCNT- geopolymer composite

Article scientifique 2020 Anglais

Résumé

Abstract The target of the present paper is to study the enhancement effect of MWCNT on geopolymer resistivity to chloride attack. Geopolymer composites were made from metakaolin and ground granulated blast furnace slag and to either 10 % silica fume or glass waste. The added MWCNT were in the ratio of 0.01: 0.09 % by weight. Results revealed the high resistivity and stability against magnesium chloride solution; in addition glass waste mixes acquired high mechanical strength as compared with silica fume mixes as related to the high amorphous structure as well as high finesty of glass waste as compared with silica fume. The results revealed an increased enhancement in characteristics of geopolymer composites with MWCNT up to 0.07 % in both matrices.
