Mathematics · Concrete Strength Calculations
Using Abrams' strength-water/cement ratio relationship expressed as: S = ABx × (6.895 × 10-3) MPa, where 'S' is the compressive strength, 'x' is the water-cement ratio by volume, and A = 6000 and B = 10 are empirical constants, estimate the compressive strength of concrete when the adopted water-cement ratio (by volume) is 0.40.
