How to Choose f'c According to ACI 318-25 Code

As a structural engineer, you know that selecting the correct f'c is the first and most important step to ensure the safety and proper performance of any concrete structure.

In this video, we'll thoroughly review the four key rules and considerations that the ACI code specifies for selecting f'c:

✅ Minimum Requirements: We'll take a close look at ACI 318 Table 19.2.1.1 to understand the minimum concrete strength required for various applications and conditions.

✅ Durability Requirements: We'll explore why both concrete strength and durability are essential and how durability requirements (based on Table 19.3.2.1) might necessitate a higher f'c than what is needed for structural strength alone.

✅ Structural Strength Requirements: We'll examine the influence of the structural system and other factors on the selection of concrete strength.

✅Lightweight Concrete Limitations: We'll learn about the specific limitations for using lightweight concrete in special seismic systems and how these limitations can be overcome.
