28-day Compressive Strength of Concrete given Force in Slab Solution

Follow our step by step solution on how to calculate 28-day Compressive Strength of Concrete given Force in Slab?

FIRST Step Consider the formula

f c = \frac{P on slab}{0.85 \cdot A concrete}

Next Step Substitute values of Variables

∴

f c = \frac{245kN}{0.85 \cdot 19215.69mm²}

Next Step Convert Units

∴

f c = \frac{245000N}{0.85 \cdot 0.0192m²}

Next Step Prepare to Evaluate

∴

f c = \frac{245000}{0.85 \cdot 0.0192}

Next Step Evaluate

∴

f c = 14999997.0918373Pa

Next Step Convert to Output's Unit

∴

f c = 14.9999970918373MPa

LAST Step Rounding Answer

∴

f c = 15MPa
