Elastic Modulus of Concrete

on . Posted in Classical Mechanics

Elastic modulus of concrete, abbreviated as \(E_c\), is valid for normal weight, normal density concrete.


Elastic Modulus of concrete formula

\(\large{ E_c =  57,000 \; \sqrt{ f_{c}{'}  }   }\)     (English units)

\(\large{ E_c =  4700 \; \sqrt{ f_{c}{'}  }   }\)     (Metric units)

Symbol English Metric
\(\large{ E_c }\) = elastic modulus of concrete \(\large{\frac{lbf}{in^2}}\)  \(\large{MPa}\) 
 \(\large{ f_{c}{'} }\)  = concrete specified cylinder 28-day compression strength \(\large{\frac{lbf}{in^2}}\)  \(\large{MPa}\)
