The objective of this course is to build the basic understanding of students on concrete ingredients and their properties, properties of fresh and hardened concrete, quality assurance and quality control in concreting works, concrete grade and concrete mix design, and special concrete. After completing this course, students should be able to develop competency in understanding on behavior of concrete, concreting operation, tests on concrete, and mix design.
