| Summary: | 碩士 === 國立屏東科技大學 === 土木工程系所 === 97 === The concrete structure in order to ensure the use of life-cycle. From the mixed proportion design, construction process and maintenance have to consider the problem for the durability of concrete. The concrete structure increase resistance to chemical attack, abrasion-erosion, weathering and other destructive forces. The use of concrete in order to enhance the life cycle.
The purpose of this study is to enhance the durability of concrete structure must be considered the item and statement. Including the durability of concrete by the fracture mechanics invasion, physical invasion and discuss with a single pozzolanic materials and at the same time add two pozzolanic materials (Fly ash and/or furnace slag) to replace cement. Comparing different pozzolanic materials in the durability feature of portland cement type I and type II concrete. Lab tests include compressive strength test, absorption test, resistivity test and gas penetration test.
