Course Curriculum

Properties of Concrete

Presents the many possible components of concrete, including the desirable properties of the chosen aggregate and water. Includes a review of chemical and mineral admixtures, fibers, and special types of concrete. Also covers the basics of concrete testing.

Estimating Concrete Quantities

Reviews basic mathematical calculations for area and volume as well as metric conversions to prepare trainees for the module topic. A review of drawings and their interpretation is also provided, along with guidance for estimating the volume of concrete needed in placements of various shapes.

Tilt-up Wall Systems

Describes how tilt-up concrete construction is used and how tilt-up panels are formed, erected, and braced. Covers the installation of rebar and types of embedments used to lift and brace the panels. Also covers methods used to create architectural and decorative treatments.

Paving

Describes paving operations, paving equipment, recycling processes, and quality control requirements for both concrete and hot-mix asphalt paving.

Architectural Finishes

Identifies and describes various architectural finishes and how they are applied. Covers the coloration of concrete surfaces and how to use form liners and stamps to create texture. Provides detailed guidance on the creation of exposed aggregate finishes.

Industrial Floors

Presents this key segment of concrete flatwork and the characteristics of industrial floors while explaining how industrial-class floors are created, including preplacement considerations.

Superflat Floors

Describes random-traffic and defined-traffic superflat floors and the flat and level characteristics that set them apart from other slabs. Provides insight into the finishing process and describes how various floor-measurement instruments are used to document the results.

Surface Treatments

Provides detailed coverage of the many methods used to prepare a concrete surface to meet a specific surface profile, from detergent scrubbing to rotomilling. Also identifies and describes how to apply shakes, protective sealants and coatings, and selfleveling toppings and underlayments.

Troubleshooting and Quality Control

Defines quality control and discusses fresh concrete troubleshooting and problem resolution. Provides detailed coverage of concrete field tests and specimen preparation according to ASTM standards.

Concrete Repair

Provides an overview of the concrete repair process, focusing on repairing concrete with concrete. Explains how hidden concrete faults and embedments are located and how to properly prepare reinforced concrete for placement of the repair material. Coverage of pre-placement and post-placements inspections is also provided.
