Abstract

In this research, early strength development performance of early strength improvement type ordinary cement which is economically feasible early strength cement(Type III), improved early strength ordinary cement(Type I), was estimated to derive minimum curing temperature and proper water to cement ratio according to cement for early strength development through examination of fresh concrete properties and compressive strength according to water to cement ratio curing $10^{\circ}C$, $15^{\circ}C$ and $20^{\circ}C$ to suggest fundamental data for practical use of early strength concrete.

본 연구에서는 3종 조강시멘트에 비해 경제성을 개선하고, 1종 보통포틀랜드시멘트에 비해 조강성능을 개선한 조기강도 개선형 시멘트를 사용한 조강콘크리트의 양생온도 및 물시멘트비에 따른 굳지 않은 콘크리트 특성 및 조기강도 발현 특성을 검토함으로써, 이를 활용한 조강콘크리트의 실용화를 위한 기초자료를 제시하고자 하였다.
