1. A method of forming an activated glass pozzolan, the method including:

reacting particles of glass in an activation solution including sodium, potassium, calcium, magnesium or manganese metal or metal hydroxide, wherein the activation solution further consists of an additive selected from lithium salts or lithium hydroxide;

wherein the activation reaction provides partially etched glass with calcium silicate hydrate (C—S—H) therein;

wherein the partially etched glass is subsequently dried after the activation reaction is completed; and

optionally grinding the dried partially etched glass with C—S—H therein;

thereby providing an activated glass pozzolan.
