本研究係探討以氧化碴取代細骨材及以還原碴取代膠結料，對高流動性低強度材料(CLSM)之強度發展影響。研究變數包括水膠比為 1.1、1.3 與 1.5；CLSM膠結料固定為 130kg/m3；還原碴取代膠結料比例為 0%、25%及 50%，一般型 CLSM 之氧化碴取代細骨材比例為 0%、50%、75%及 100%，早強型 CLSM之氧化碴取代細骨材比例為 0%、50%及 100%。研究結果顯示，利用氧化碴與還原碴可製作出坍度大於 20 cm、28 天齡期抗壓強度小於 30kg/cm2之 CLSM 材料。當氧化碴取代細骨材比例愈高時，不銹鋼爐碴 CLSM 之超音波波速亦愈高，並且凝結時間相對減少。不銹鋼爐碴 CLSM 之還原碴取代膠結量愈高時，其凝結時間愈長，而超音波波速與抗壓強度則相對降低。

The purpose of this research is to determine the compressive strength of the Controlled Low Strength Materials (CLSM) containing both the Stainless Steel Oxidizing Slag (SSOS) and the Stainless Steel Reducing Slag (SSRS). The test variables include the general type (28-day
compressive strength < 30 kg/cm2 ) and the early type (1-day compressive strength > 5 kg/cm2). The binder amount is 130 kg/m3 , and water to binder ratio (W/B) are 1.1, 1.3 and 1.5. 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 show utilizing SSOS and SSRS can produce CLSM which slump larger than 20 cm. The compressive strength of 28 days of CLSM consists of the Stainless Steel Slag less than 30 kg/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 of CLSM increase relatively.
