Question

A normal weight concrete has an average compressive strength of 16 MPa. What is the estimated flexural strength?

Answer 1

The answer is "24.5333334 MPa"

Step-by-step explanation:

The flexure intensity of standard concrete is estimated approximately by increasing a pressure distribution to (
`(2)/(3)`).

The frequency of the pressure = 20 MPa

`\ Flexure \ strength = 2.3 * (16)* (2)/(3) \ MPa\\\\`

`= 2.3 * (32)/(3) \ MPa\\\\= 2.3 * 10.6666667 \ MPa\\\\= 24.5333334 \ MPa\\\\`
