Reaction of quartz glass in lithium-containing alkaline solutions with or without Ca [PDF]
Royal Society Open Science, 2018 The exact role of lithium ions (Li+) in controlling alkali–silica reaction is still unclear. Thus, the effects of Li+ on the reaction between reactive silica (quartz glass) and hydroxyl in alkaline solution with or without Ca were investigated by quartz ...
