As a result, it was found that raising curing temperature enhanced silica fume reactivity and it significantly contributed to the improvement of strength development. Additionally it was found that it was important to enhance cement reactivity by maintaining higher temperature in order to acquire higher strength. It was experimentally shown that compressive strength could be expressed in the strength formula based on gel space ratio theory in this strength level. Additionally, according to the evaluation based on gel space ratio theory, silica fume had higher effect on strength per consumption compared to cement.Read More
