Geopolymer Damage Due to Leaching When Exposed to Water

An investigation on the effect of water immersion on the compressive strength of geopolymer pastes was investigated. Specimen’s exposure to water showed a detrimental effect on the compressive strength of the geopolymer pastes (up to 25% strength loss). It was shown that the leaching of the sodium silicate when geopolymers were immersed in water decreases the compressive strength.
