Target Mean Strength for Mix Design Solution

STEP 0: Pre-Calculation Summary

Formula Used

Target Average Compressive Strength = Characteristic Compressive Strength+(1.65*Standard Deviation of Distribution)
f'_ck = f_ck+(1.65*σ)
This formula uses 3 Variables

Variables Used

Target Average Compressive Strength - (Measured in Pascal) - Target Average Compressive Strength is the design strength determined for the manufacture of reinforced concrete. It is measured as the strength of concrete after 28 days of curing.
Characteristic Compressive Strength - (Measured in Pascal) - The Characteristic Compressive Strength is the strength of the concrete below which not more than 5% of the test results are expected to fall.
Standard Deviation of Distribution - Standard Deviation of Distribution is a measure of how spread out numbers are.

STEP 1: Convert Input(s) to Base Unit

Characteristic Compressive Strength: 20.01 Megapascal --> 20010000 Pascal (Check conversion here)
Standard Deviation of Distribution: 4 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f'_ck = f_ck+(1.65*σ) --> 20010000+(1.65*4)

Evaluating ... ...

f'_ck = 20010006.6

STEP 3: Convert Result to Output's Unit

20010006.6 Pascal -->20.0100066 Megapascal (Check conversion here)

FINAL ANSWER

20.0100066 ≈ 20.01001 Megapascal <-- Target Average Compressive Strength
