Abstract

Nowadays, due to the development of industrial and civil engineering technology, enlargement and diversification of concrete structures are being tried. At the same time, the hydration heat generated during the construction of large structures lead to thermal crack, which is occurs causing a problem that durability degradation. In this paper, in order to study the durability and reducing hydration heat of concrete according to the types of cement, that is ordinary portland cement, fly ash cement mixed with a two-component, ternary blend cement mixed with fly ash and blast furnace slag and low heat cement concrete are produced, and compare and analyze the results using property, durability and hydration characteristics, ternary blend cement is appeared to be the most excellent in durability and reduction of hydration heat, and it was determined suitable for construction of mass concrete and requiring durability.

현재 산업 및 토목기술의 발전으로 인한 콘크리트 구조물의 대형화 및 다양화가 시도되고 있으나 대형 구조물의 시공 시 발생하는 수화열은 온도균열을 유발하여 콘크리트 구조물의 내구성능을 저하시키는 문제를 발생한다. 본 논문은 시멘트의 종류에 따른 콘크리트의 내구성능 및 수화열 저감 특성을 고찰하기 위하여 보통포틀랜드시멘트, 플라이애쉬를 혼합한 2성분계 시멘트, 플라이애쉬와 고로슬래그를 혼합한 3성분계 시멘트 및 저발열 시멘트를 각 각 사용하여 제작한 콘크리트의 물성, 내구성능 및 수화특성 등의 결과를 비교 분석한 결과, 3성분계 혼합 시멘트가 내구성능 및 수화열 저감 효과에 가장 우수한 것으로 나타나 매스 콘크리트 및 내구성능이 요구되는 구조물 축조에 적합하다고 판단되었다.
