Effect of organic resin in glass wool waste and curing temperature on the synthesis and properties of alkali-activated pastes

This study investigated the effect of organic resin contained in glass wool on synthesis of alkali-activated binders. The study was performed on glass wool containing sugar or phenolic resin, comparing it with glass wool that did not contain resin, as a reference. The results showed that the organic...
