下水污泥灰渣已被證明具有卜作嵐活性，可將其摻入水泥砂漿中取代部分水泥。對於含有下水污泥灰渣之砂漿，過去研究著重於其工作性及抗壓強度的探討，對於污泥灰渣砂漿其他重要工程性質，例如抗彎強度、衝擊強度，以及乾縮行為等，尚缺乏有系統之探討。基於以上理由，本研究採取台北民生污水處理廠下水污泥，以模具式焚化爐製備污泥灰渣，並用於製作污泥灰渣砂漿試體，以探討前述重要工程性質。此外，本研究選用微鋼纖維、啞鈴型鋼纖維，以及兩種聚丙稀纖維材料，摻入前述污泥灰渣砂漿，探討以纖維材料改良砂漿工程性質之可行性。
由實驗結果發現，隨著灰渣取代水泥量的增加，將降低污泥灰渣砂漿之抗壓、抗彎強度，並且增加其乾縮量。另一方面，與純水泥砂漿相較而言，污泥灰渣砂漿之工程性質，包含抗壓強度等，均不及同齡期之純水泥砂漿。基於以上研究結果證實，改善污泥灰渣砂漿工程性質之研究有其必要性。
就纖維材料改良砂漿工程性質方面，本研究以水泥取代量20%之污泥灰渣砂漿為研究對象，並添加上述四種纖維於污泥灰渣砂漿。研究結果證實，添加微鋼纖維於污泥灰渣砂漿中，對於污泥灰渣砂漿強度之改善具有顯著的效果，啞鈴型鋼纖維雖然也有提高強度的能力，但是其效能不如微鋼纖。至於聚丙稀纖維，具有提高污泥灰渣砂漿衝擊強度的能力，但是對於抗壓以及抗彎強度，則無明顯改良的效果。因此，本研究實驗結果發現，使用鋼纖維改良污泥灰渣砂漿工程性質，較聚丙稀纖維具有可行性。

The sewage sludge ash (SSA) has been proved to exhibit certain pozzolanic activity and can be reused in mortar to replace partial cement. However, the previous research works focused on the workability and compressive strength of SSA mortar and many other properties, including flexural strength, impact strength, and drying shrinkage of SSA mortar, has seldom been discussed. For this reason, this study selected the sewage sludge of Ming-Shen Community WWTP and prepared SSA from a modular incinerator. The prepared SSA sample was further applied into mortar to obtain SSA mortar. Consequently, the properties of SSA mortar, including compressive strength, flexural strength, impact strength, and drying shrinkage were analyzed. In addition, in order to enhance the properties of SSA mortars, four types of fiber material have been applied into SSA mortar. These fibers include two types of steel fiber, i.e. micro and enlarged-end, and other two types of polypropylene fiber.
According to the test results, the compressive and flexural strength of SSA mortars, generally decreased with increasing application amount of SSA. In contrast, the amount of drying shrinkage of SSA mortar generally increased with increasing application amount of SSA. When comparing with pure cement mortar, the SSA mortars exhibited lower strength and higher amount of drying shrinkage. This result revealed the necessity of the modification of SSA mortars.
Regarding the application of fiber material, the cement replacement ratio of the tested SSA mortars was 20%. The test results indicated that, the micro steel fiber exhibited superior effects on the simultaneous enhancement of the compressive strength, flexural strength, and impact strength of SSA mortar. The enlarged-end steel fiber could also improve the strength of SSA mortar, however it was less effective than micro steel fiber. In addition, the two types of polypropylene fiber could only improve impact strength of SSA mortar. Thus the effectiveness of polypropylene fibers on improving properties of SSA mortar was less than that of steel fibers.
