Study on the Properties of the Low Heat Concrete Applied to the Mass Concrete by the Blended Cements
혼합시멘트를 사용한 저발열콘크리트의 매스콘크리트 적용을 위한 기초특성 연구
Abstract
Considering properties of the low-heat concrete mixed with the blended cements, the influences compared blended cements with ordinary portland cement made experiments on. (1) Blended cements were superior to OPC in the fresh concrete flow that the use of blended cements reduced chemical admixture. (2) The more the use of additive increase, the more bleeding happens. So it is considered to heights, order, and rate of placement, curing methods and so on. (3) The use of blended cements increase long term strength after 28 days, but decrease early strength and durability. So it is considered to the curing methods and early frost damage, and endurance limit.
