| 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 === 93 === The purpose of the research is to explore the feasibility and property of the CLSM (Slump>20cm) when the SSOS replace the fine aggregate and the SSRS replace the binder. The variables of research include the ordinary shape(compressive strength in the twenty-eighth day＜30 kg/cm2) and the early shape(compressive strength in the first day＞5 kg/cm2). The value of the binder is about 130 kg/m3 to result that W/B is 1.1, 1.3 and 1.5, respectively. The weight ratios of SSOS replacing the fine aggregate are 0%, 50%, 75% and 100%. The weight ratios of the SSRS replacing the binder are 0%, 25%, and 50%. The results shows utilizing the SSOS and the SSRS can produce the CLSM meeting the requirement of the engineering property. Whether W/B is 1.1, 1.3 or 1.5, the property of the ordinary shape stainless steel slag CLSM will meet the goal when the ratio of SSRS replacing binder is 50% and the ratio of the SSOS replacing the fine aggregate is 50% or 100%. In terms of workability, the heavy specific gravity of the fine aggregate deposit easily to cause the segregation of the fine aggregate when the SSOS replacing fine aggregate will reach 100%. Whether W/B is 1.1, 1.3 or 1.5, the property of the early shape in stainless steel slag CLSM will meet the property of engineering when the ratio of SSRS replacing binder is 0% and the ratio of the SSOS replacing the fine aggregate is 50%. In the engineering property, the twenty-eighth day of compressive strength in stainless steel slag CLSM mostly conforms to prospected 30kg/cm2. As the SSOS replace the fine aggregate more, the unit weight and pulse velocity of CLSM raise, but the setting time reduce. As the SSRS replace the binder more, the pulse velocity and the compressive strength of CLSM reduce, but the setting time raise. Form the study results, it is found that the pulse velocity, rebound hammer and compressive strength have a good correlation.
