Error curves using linear with and without intercept and power function: (a) 50-mm cubes to 100-mm cubes; (b) 50-mm cubes to 75 × 150 mm cylinders; (c) 100-mm cubes to 75 × 150 mm cylinders (f_exp=experimental strength, f_pred=predicted strength, f₇₅ = 75 × 150 mm cylinder strength, f₁₀₀ = 100 × 100 mm cube strength, f₅₀ = 50 × 50 mm cube strength).
