ACI Adhesive Anchor Installer Certification Practice Exam

Why is it important to inspect an anchor before use?

1. To confirm weight capacity

2. To ensure it is dry, clean, straight, and marked

3. To check for brand quality

4. To verify length accuracy

The correct answer is: To ensure it is dry, clean, straight, and marked

Inspecting an anchor before use is crucial because it ensures that the anchor is dry, clean, straight, and properly marked. Each of these factors significantly affects the performance and reliability of the adhesive anchor. A dry anchor prevents the introduction of moisture that could interfere with adhesive bonding, while a clean anchor ensures there is no contamination that might weaken the bond. If an anchor is bent or deformed, its ability to hold under load could be compromised. Proper markings help identify the anchor type and its specifications, assisting the installer in using it accurately according to the manufacturer's guidelines. While confirming weight capacity, checking for brand quality, and verifying length accuracy are important considerations in selecting an anchor, they are secondary to ensuring the condition of the anchor itself at the moment of installation. Thus, inspecting for cleanliness, dryness, and proper physical condition is foundational to achieving a successful anchor installation.
