ACI Adhesive Anchor Installer Certification Practice Exam

MPII includes directions for which of the following?

1. Visual inspection procedures

2. Drilling the hole and filling the hole

3. Only for cleaning the area

4. Testing the anchor after installation

The correct answer is: Drilling the hole and filling the hole

The correct choice focuses on the procedures involved in drilling the hole and filling the hole with adhesive, which is a critical aspect of the installation process for adhesive anchors. The MPII (Method of Performance for Installation Instructions) provides detailed guidelines on how to properly prepare the hole in the substrate, including the size and depth necessary, and how to effectively install the adhesive within that hole to ensure optimal bond strength between the anchor and the surrounding material. When following MPII, it's important that the process of drilling is done correctly to avoid damaging the substrate, which could compromise the stability of the anchor. Additionally, filling the hole correctly is essential, as it ensures that the adhesive makes proper contact with the entire surface of the hole, creating a strong bond that will hold the anchor in place under load. While visual inspection procedures, cleaning the area, and testing the anchor after installation are all vital parts of the overall installation process, they belong to different components of the instruction set or various best practice standards. The focus of MPII primarily rests on the technical execution of drilling and filling the hole with adhesive, which directly impacts the effectiveness of the adhesive anchor installation.
