ACI Adhesive Anchor Installer Certification Practice Exam

What type of adhesive anchor systems provides an alternative to cartridge anchor systems?

1. Cylinder adhesive systems

2. Pre-mixed adhesive systems

3. Capsule adhesive systems

4. Liquid adhesive systems

The correct answer is: Capsule adhesive systems

Capsule adhesive systems serve as a viable alternative to cartridge anchor systems due to their unique design and application process. These systems consist of a capsule containing pre-measured amounts of adhesive and hardener, which are mixed together as they are dispensed into the drilled hole. This mixing occurs automatically as the adhesive is expelled from the capsule, ensuring a consistent and accurate ratio of components that leads to optimal bonding strength. One of the key advantages of capsule adhesive systems is their ease of use and reduced chance of mixing errors, which can sometimes occur with manual mixing required in cartridge systems. Additionally, the encapsulated format helps protect the adhesive from contamination and allows for longer shelf life, thus enhancing the reliability of the anchoring process. By understanding how capsule adhesive systems work and their benefits, individuals in construction and installation can make informed choices about which type of adhesive anchor systems to use based on project requirements and conditions.
