Effect of temperature on leaching alkali metal ions from waste glass powder used as an additive to portland cement

Resumo

Leaching is considered as a means of reducing the alkalinity of glass powders produced from waste container glass and employed as additives to portland cement. The temperature of a leaching agent is established to be a key factor affecting the efficiency of the procedure. Also, for optimal leaching, the glass powder needs to be exposed only once to hot (close to boiling) water—a leaching agent—and only for a short period.
