Question

What is the minimum 28 day compressive strength for lightweight aggregate concrete?

1) 2500 psi
2) 3000 psi
3) 3500 psi
4) 4000 psi

Answer 1

The minimum 28-day compressive strength for lightweight aggregate concrete is typically 2500 psi to 3000 psi.

Step-by-step explanation:

The minimum 28-day compressive strength for lightweight aggregate concrete is typically 2500 psi (pounds per square inch) to 3000 psi. Therefore, the correct answer is option 1) 2500 psi.
