| Summary: | 碩士 === 國立雲林科技大學 === 營建工程系碩士班 === 90 === The objective of this study is to investigate the workability, compressive strength, and durability of concrete using waste glass and steel slag to replace the fine aggregate. The waste glasses and steel slag used for concrete include powders with 3000 and 5000 Blaine to replace 5%, 10% and 15% of fine aggregate in concrete mixture. Test results show that 3000 Blaine of waste glass can improve the workability of fresh concrete, but the 5000 Blaine of waste glass and steel slag can’t. The compressive strength of concrete is higher than the control. The durability of concrete (including the thaw-freeze resistance, the chloride permeability, the anti-carbonation properties) can be improved by adding waste glass and steel slag in concrete, but the abrasion properties is lower than control. The drying shrinkage of mortar with waste glass and steel slag is higher the control. The microstructure analysis shows that the pozzolanic reaction occurs in cement paste with waste glass and steel slag powder.
