Elastic Modulus of Concrete

Written by Jerry Ratzlaff 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)

Where:

 Units 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 \(\large{\frac{lbf}{in^2}}\) \(\large{MPa}\)
