ACI Adhesive Anchor Installer Certification Practice Exam

What is the purpose of the dispenser in the adhesive anchor system?

1. To hold the adhesive

2. To mix the components

3. To apply pressure

4. To allow flow into the mixing nozzle

The correct answer is: To allow flow into the mixing nozzle

The purpose of the dispenser in the adhesive anchor system is to allow flow into the mixing nozzle. This component is carefully designed to ensure that the adhesive components are correctly mixed just before application. The mixing nozzle is essential for combining the resin and hardener evenly, which is crucial for achieving the desired bond strength and setting properties of the adhesive. While the dispenser does indeed hold the adhesive, its primary function goes beyond just containment. The ability to provide appropriate pressure to push the adhesive through the mixing nozzle helps guarantee that the two components are thoroughly combined at the point of application, minimizing the risk of improper bonding due to inadequate mixing. Thus, its design prepares the adhesive in a controlled manner, enhancing the overall effectiveness of the adhesive anchor installation process.
