CE72.41 : Advanced Concrete Technology  3(3-0)
 
Course objectives:

The objective of this course is to provide students with advanced knowledge of concrete technology which covers properties of fresh concrete, hardened concrete including strength, dimensional stability such as thermal shrinkage, drying shrinkage and creep, durability of concrete including permeability, classification of concrete deterioration such as physical deterioration, chemical deterioration and mechanical deterioration, and guide to durable concrete, and the concept of designs of mix proportion for normal concrete and special concretes. Durability of concrete structures will be discussed more in details. New concrete-making materials including conventional and recent admixtures and recent advancements in concrete technology, namely lightweight concrete, high-strength concrete, high performance concrete, shrinkage-compensating concrete, fiber-reinforced concrete, self-compacting concrete, concrete for repairing, pervious concrete, preplaced aggregate concrete, underwater concrete and mass concrete  will also be included as well as special topics on premixed dry mortars and special mortars.

 
Learning Outcomes:
On successful completion of this course, the students will be able to:
  • synthesize knowledge to solve any practical problems related to advanced concrete technology.
  • design special concrete to meet any requirements.
