Class Objectives
/Class Outline To deeply learn chemical properties of concrete necessary to produce highly durable and high performance concrete and to maintain existing concrete for the long term regarding concrete with which civil infrastructures are constructed.
The evaluation items of 'knowledge and understanding' and 'ability and skill' are as follows:
1. To understand the chemical properties of constituent materials for concrete, and to explain factors inducing durability problems of concrete ((B) ability to find problems)
2. To qualitatively explain substance migration in concrete related to chemical durability ((B) ability to find problems)
3. To propose measures against principal chemical deterioration of concrete ((B) ability to find problems)
