# Elastic Modulus of Concrete

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

## Elastic Modulus of concrete formula

 $$\large{ \lambda_c = 33 \; W_c^{1.5} \; \sqrt{f_c} }$$ $$\large{ \lambda_c = 57,000 \; \sqrt{f_c} }$$

### Where:

$$\large{ \lambda_c }$$  (Greek symbol lambda) = elastic modulus of concrete

$$\large{ f_c }$$  = compressive strength of concrete

$$\large{ W_c }$$  = weight of concrete
