Course Overview
Details the initial testing performed on concrete including slump, air entrainment, unit weight and temperature. Topics include maintenance and calibration of test equipment; procedures for preparing and curing samples; capping and testing compression cylinders; preparing and conducting flexural tests; interpreting test results. The problem areas in concrete preparation and placing that should be inspected, and the appropriate actions to be taken in the event of non- conformance with specifications are detailed. Access to a local laboratory will be required to demonstrate competency in the testing practices.

Learning Outcomes
Upon successful completion, the student will be able to:
Module 1 - Sampling Fresh Concrete
- Discuss the relationship between the required concrete tests and the role of the concrete inspector.
- State and define the procedures for obtaining representative samples of fresh concrete from the most common sources.
- List and describe in general terms the tests that are performed on fresh concrete samples.
- Determine the size of sample required for the most common tests performed on fresh concrete.
Module 2 - Slump Test
- State the importance of slump tests and the typical slump range of slump values for various types of construction.
- State and describe the procedures for conducting slump tests on fresh concrete in preparation for conducting the actual tests.
Module 3 - Air Content and Density Tests
- State and describe the procedures for the calibration of an air meter for both percentage air and density tests.
- List and describe in general terms the apparatus, its features and the associated tools in preparation for the actual conducting of an air content test using an air meter.
- List and describe the apparatus, its features and the associated tools required to conduct an air content test using the volumetric method.
- List the steps required and complete the calculations to determine the density of fresh concrete using an air meter.
Module 4 - Compression Specimens and Tests
- State the requirements for casting specimen cylinders for compressive strength testing, including handling and site storage for initial curing.
- State and discuss the requirements for controlled curing and preparation of cylinders for compression testing.
- State and discuss the loading, recording and perform the calculations to determine the compressive strength of concrete test specimens.
- Perform the above procedures and tests in a manner that results in industry standard results.
