Summary: | 碩士 === 國立高雄應用科技大學 === 土木工程與防災科技研究所 === 103 === This study was to evaluate fresh and hardened concrete performance, when three recycling green materials, namely the waste liquid-crystal display (LCD), steel slag, and fly ash were added for concrete mixing. The concrete specimens were moist cured in two different types of hot spring water obtained from Chiaohsi Township at Ilan County and Chihpen Township at Taitung County in Taiwan. When the addition of recycling green materials increases, fresh and hardened concrete properties including slump (11.1% to 66.7%), setting time (7.56%), compression strength (11.6% to 13.41%) increase and the unit weight decreases. In addition, the test results of pulse velocity (4556 to 4773 m/s), shear wave velocity (4602 to 4751 m/s), of chlorite content (0.014 to 0.031 kg/m3), ten-time increase of surface resistance, thermal conductivity (0.8631 to 1.3787 W/m˙k), and good sulfate resistance imply the use of recycling green materials improve the engineering properties of concrete in comparison of the Ordinary Portland Cement concrete (280 kg/cm2). The outcomes of this study provide a good reference in mix proportion and potential performance of concrete containing green recycling materials.
