Course description and aims

This course is a laboratory class focusing on the material property of the concrete and mechanical behavior of reinforced concrete.
It is requested for concrete to meet with several requirements; fresh property to make casting work easy and sure and physical and chemical property of hardened concrete to make concrete structure rigid and durable. In this course, students understand the fresh property through learning design method of mix proportion and to meet with requested performance, and mix the designed concrete by themselves. And they also understand the physical and chemical property of hardened concrete through some physical and chemical tests on the hardened concrete.
In the classes on the reinforced concrete, students learn how a reinforced concrete structure is made and how they fail through the experimental work. And in the creative design competition, students get an experience of setting group goal and strategy to tackle a task, building consensus about them in the group, and overcoming technical challenging to achieve the group goal with integrating their knowledge and experiences.
This course aims to cultivate the basis of civil engineers through the experimental works. Students are expected to understand deeply the property of concrete, the mechanical behavior of reinforced concrete structures, and get an experience of the group management in engineering.

Student learning outcomes

By the end of this course, students will be able to:
1) Understand the designing method of concrete mix proportion and decide the mix proportion to meet the requested performance.
2) Learn the test of fresh concrete, and explain the property of fresh concrete.
3) Learn the test of hardened concrete, and explain the physical and chemical property of hardened concrete.
4) Explain the fracture process of reinforced concrete members and the difference in failure pattern.
5) Explain the making process of reinforced concrete members.
6) Propose a group goal and strategy to tackle the task and build consensus for them.
7) Implement the strategy to achieve the goal by integrating the knowledge about the property of cementitious material and structural design.
