碩士 === 國立高雄應用科技大學 === 土木工程與防災科技研究所 === 105 === Research bagasse ash with Alkaline Solution as the main material to make Inorganic polymers. The modulus of sodium silicate 0.6, 0.8 and 1.2, various dosages of activator 6%, 8% and 10% and fixed water-solid ratios 0.35 and 0.4, to assess on the engineering properties. The research results show that: First, when bagasse ash replacement higher, its flowability gets worse. Second, when modulus of sodium silicate increases then the slump and slump flow decrease. Third, 10% of bagasse ash replacement which compressive strength and sulfate resistance’s effect is optimal. Forth, 20% bagasse ash replacement, its drying shrinkage phenomenon is the smallest. Fifth, curing into saturated limewater of compressive strength is less than curing at atmospheric conditions, then curing into saturated limewater of drying shrinkage phenomenon is lower than curing at atmospheric conditions. Finally, when bagasse ash replacement form 0% to 20%, its water resistance of softening coefficiency is greater than 0.85, therefore bagasse ash replacement form 0% to 20% is suitable for waterproof material.
