Brief History of Structural Concrete
1824 Patent on Portland Cement (Aspdin)1854 Reinforced Concrete (Wilkinson)1886 First prestressing system using tie-rods
" Compressive strength : fcu or fc’(≈ 0.8fcu)(28-day characteristic)
" Tensile strength: ft’ = 0.1~0.2 fc’
" Modulus of rupture: fr = 0.623√fc’> ft’ (ACI)
" Modulus of elasticity: Ec= 4730 √fc’ (MPa)
