| Summary: | 碩士 === 國立雲林科技大學 === 營建工程系碩士班 === 90 === The objective of this research is to investigate the strength, workability, durability, and the microstructure of concrete using the waste fluid catalytic cracking catalysts to replace cement in mortar and high performance concrete (HPC).
The test methods in mortar and concrete include: Compressive strength, abrasion properties, fast chloride permeability, and thaw-freeze resistance. The test methods in cement paste include: SEM, X-Ray diffraction pattern, and Nuclear Magnetic Resonance (NMR).
Test results show that waste catalysts and fly ash, waste catalysts and slag to replace cement in mortar and HPC can improve workability, compressive strength, and the chloride penetration of the durability of concrete. Using waste catalyst and fly ash, waste catalyst and slag substitute cement in mortar and concrete, the compressive strength in all curing ages, and workability are higher than 0%. Using waste catalyst and fly ash, waste catalyst and slag substitute cement in concrete, the chloride permeability is lower than 0% in all curing age.
The microstructure of SEM analysis shows the pozzolanic reaction in cement paste with waste catalysts. The X-Ray diffraction test shows the waste catalyst consume CH in pozzolanic reaction.
