文摘

Proposing two new alternative curing method are using preheated materials and thermogentic admixtures. For using preheated materials, a larger amount of preheated materials results in a higher compressive strength. For using thermogentic admixtures, quicklime is more efficient than hot pack material. The suggested amount of quicklime is about 3–5% of fly ash by mass.
