Description

Overview

Building owners and developers must ensure they get what they contracted for in terms of building quality. To that end, architects and engineers want to be sure the building is constructed to their specifications so that it performs as designed. Various concrete tests are the foundation of determining its quality and future serviceability. This module will review proactive steps taken by contractors and the field-testing procedures used by concrete craftworkers to deliver the best product possible.

 

Learning Objective 1 – Successful completion of this module prepares trainees to:

Describe quality control processes and explain how to complete the necessary tasks to ensure compliance with project specifications.

    1. Define quality control and explain how contractors are apprised of quality expectations.
    2. Describe the scope of pre-placement inspections required to ensure acceptable results.
    3. Explain how to organize and conduct a troubleshooting process.
    4. Identify common problems encountered in fresh concrete and how they might be resolved.

Learning Objective 2 – Successful completion of this module prepares trainees to:

Explain how to collect concrete samples, prepare specimens, and complete various field tests.

    1. Explain how to organize and collect concrete field samples.
    2. Explain how to prepare specimens for strength testing.
    3. Explain how to perform a slump test.
