A Proposal of Elastic Modulus Equation for High-Strength and Ultra-High-Strength Concrete

국내 실정에 적합한 고강도 및 초고강도 콘크리트의 탄성계수식 제안

The aim of this study is to suggest the new elastic modulus equation that suits to a domestic situation to coincide the improved mechanical properties of high-strength concrete and ultra-high-strength concrete. For thish purpose, this study collected the laboratory data more than 400 connceted with the the modulus of elasticity that performed in this country and also analyzed it statistically. The compressive strength of investigated concrete ranged from 400 to 1,400kg/$\textrm{cm}^2$. As a result, a practical and useful elastic modulus equation is proposed, it can be considered as most suitable equation in domestic situation.
