Abstract
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.
