| Summary: | 碩士 === 國立雲林科技大學 === 營建工程系碩士班 === 94 === The objective of this research is investigating the strength, workability, durability, and the microstructure of concrete using the waste fluid catalytic cracking catalysts to replace cement in self-compacting concrete (SCC), the test methods in self-compacting concrete include: Flowing, U-test, V-test, Compressive strength, Chloride permeability, SEM and XRD.
Test results show that concrete will have the best workability when the waste catalyst substitutes for cement 5%, but workability is worse when the waste catalyst substitution quantity increase and make the concrete is easy to accrue voids, it caused cement substituted for waste catalyst 0％ of concrete’s compressive strength better then waste catalyst 10％, 15％ and 20％ of concrete’s 1.22％~15.73％
In the same curing time, the chloride permeability of concrete decrease progressively along with the waste catalyst substitution quantity increase, the voids reduce inevitably after the effect of them be filled promote, the impermeability and the chloride permeability of concrete will promote to improve the compressive strength and the durability of SCC.
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.
