摘要: This research study used metakaolin as a raw material, mixed solution of sodium hydroxide and silicate an alkali excitant, graphene dispersant additive to manufacture geopolymer sample. The compressive strength bending the sample were tested. results showed that hydration products observed be more compact, internal porosity was reduced after addition graphene. strengths had been obviously increased, reached 46.9MPa 6.7MPa, respectively. However, graphene’s role in improving original became gradually weakened when amounts increased certain extent. Furthermore, determined decrease with increase content excitant.
