Course Outline
Roller Compacted Concrete (RCC) is used to provide a more efficient and cost effective alternative to conventionally placed concrete. This course will provide information on RCC and how it compares to conventionally placed concrete. The course materials are based solely on the engineer manual "Roller-Compacted Concrete" as found on the website of the Army Corps of Engineers. This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.
