本研究以新型絕緣材料(NIM)當作主體，將新型絕緣材料與飛灰(FA)或爐石粉(GGBFS)均勻拌合，設計出絕緣漿體。絕緣漿體在變數上之設計，使用3種不同水固比(W/S=0.6、0.8、1)，將新型絕緣材料之漿體搭配4種不同比例之卜作嵐材料，飛灰(FA content=0%、10%、30%、50%)、水淬高爐石粉(GGBFS=0%、10%、30%、50%)，共設計出21組配比，灌注之試體在25℃室溫下養護。進行物理性質試驗(抗壓強度、超音波波速、熱傳導係數、假比重、吸水率、長度變化量、耐火性)，最後根據各種配比進行結果分析與討論。研究顯示：添加燃煤飛灰，抗壓強度、超音波波速，熱傳導率、假比重降低，吸水率增加；添加水淬高爐石粉，熱傳導率、耐火試體背溫降低，抗壓強度、超音波波速、假比重增加。將熱傳導率與硬固性能之關係做比較，熱傳導與抗壓強度、超音波速、假比重有正比關係；熱傳導與水固比、吸水率有反比關係，配比100NF50有最低熱傳導率，配比60NS50有最高抗壓強度。水固比0.6，厚度20mm之試體，大致能達到1小時之防火時效。

In this study, New Insulation Material (NIM) was used as the main cementitious material to prepare heat-insulating paste. Fly Ash (FA) and Ground-Granulated Blast-Furnace Slag (GGBFS) used to replace NIM by 10%, 30% and 50% bay volume while a mixture with 100% NIM was used as reference mixture. The heat-insulating paste was designed using three different water-solid ratios (0.6, 0.8, and 1). Twenty-one mix-proportions were prepared and cured under ambient temperature curing (25oc). Compressive strength, ultrasonic pulse velocity, thermal conductivity, apparent specific gravity, water absorption, drying shrinkage (length change) and fire resistance tests were conducted to the study the performance of insulation paste in different proportions of FA and GGBFS and different water-solid ratios. The results revealed that the higher inclusion of FA reduced the compressive strength, ultrasonic pulse velocity, thermal conductivity, and apparent specific gravity while water absorption was increased. On the other hand, the higher content of GGBFS will reduce thermal conductivity and back temperature of fire resistance as compressive strength; ultrasonic pulse velocity and apparent specific gravity were improved. Thermal conductivity has a direct proportional relationship with compressive strength, ultrasonic pulse velocity, and apparent specific gravity; while it has an inverse relationship with water-solid ratio and water absorption. Group 100NF50 has the lowest thermal conductivity and 60NS50 has the highest compressive strength. The test specimen with a water-solid ratio of 0.6 and a thickness of 20mm can achieve a fire aging of about 1 hour.
