ACI Adhesive Anchor Installer Certification Practice Exam

Before use, what condition must an anchor meet?

1. It must be coated with rust-resistant material

2. It must be dry, clean, straight, and marked with embedment depth

3. It must be tested for strength

4. It must be manufactured from stainless steel

The correct answer is: It must be dry, clean, straight, and marked with embedment depth

The condition that an anchor must meet before use is that it must be dry, clean, straight, and marked with embedment depth. This requirement ensures that the adhesive bond between the anchor and the base material is effective. If the anchor is not clean, there could be debris or contaminants that interfere with the adhesive's performance, leading to a weak connection. Similarly, if the anchor is not dry, moisture can also compromise the adhesion. Additionally, having the anchor straight is crucial for proper alignment and load distribution once installed. Lastly, markings for embedment depth provide guidance to the installer, ensuring that the anchor is placed at the correct depth to achieve the necessary performance specifications and to avoid any failures during operation. In contrast, while rust-resistant material and stainless steel might offer benefits in terms of longevity and corrosion resistance, they are not prerequisites for all anchor types. Testing for strength, while important in ensuring the overall integrity of an anchor, is not a preliminary usage condition that applies universally before installation.
