: 8 A Concrete Pavement Is Tested For Indirect Tensile Strength For 4 Samples Of 375 Psi 400 Psi 425 Psi And 750 Psi At 1 (1.88 MiB) Viewed 18 times

8. A concrete pavement is tested for indirect tensile strength for 4 samples of 375 psi, 400 psi, 425 psi and 750 psi at 7 days. What is the average compressive strength at 28 days if we assume 28 days compressive strength is 50% more than 7 days strength? (3 points)
