It covers the responsibilities of the purchaser and the manufacturer of ready mixed concrete. The second part of the course covers the Building Code requirements for concrete materials (ACI 318) and covers specifications for concrete as addressed in ACI 301, Specification for Structural Concrete. The presentation covers strength and durability requirements for concrete as addressed in ACI 318 and ACI 301.
Course Objectives
By the end of this course, you will be able to:
  • Describe the difference between a code and a specification
  • Outline the requirements for the strength of concrete
  • Discuss the durability, exposure classification and the associated requirements for concrete mixtures
  • Describe the scope of ASTM C94 and the responsibilities of the manufacturer and the purchaser
  • Discuss the process of ordering ready-mixed concrete
  • Identify the requirements for concrete production facilities
  • Summarize the requirements for the delivery of ready-mixed concrete
  • Discuss the acceptance testing of ready-mixed concrete

By (Engineer) on Mar, 31, 2021
Great course! Great format, instructor presentation. It would be nice to have the standard deviation formulas directly inserted into the print-version of the course, similar to the graphics sequential to the computer-based lesson. This was a great setup and there should be more courses formatted like this one. Thanks for providing.
