This course focuses on the material characteristics of concrete as one of important construction materials, and also provides fundamental knowledge essential to design and construction of infrastructure. This course covers the fundamental knowledge on constituent materials of concrete and their characteristics, properties of fresh concrete, properties of hardened concrete including durability, the concept of mixture design of concrete and the standard method, and production and execution of concrete on site.
While there are many kinds of construction materials, concrete is used the most in construction project of infrastructure. Concrete is a kind of composite materials, consisting of water, cement, fine aggregate (sand), coarse aggregate (gravel), and etc. It is quite important to understand the characteristics of these constituent materials. We have to know the properties of hardened concrete as well as fresh concrete, which is not hardened yet. Civil engineers should have the ability of designing the mixture proportion of concrete to satisfy the requirement.
By the end of this course, students will be able to:
1) Understand the characteristics of constituent materials of concrete as one of major construction materials.
2) Understand the properties of fresh and hardened concrete.
3) Conduct basic design of mixture proportion of concrete.
4) Apply practical knowledge on production and durability of concrete to design and construction of infrastructure.
