台灣地區水庫淤積快速，此問題日益嚴重，為保使水庫的有效容量因此進行水庫浚渫的工作以延長水庫之壽命，但大量疏濬出來的淤泥難以處置，應予資源化利用，本研究探討水庫淤泥燒製成建築用輕質骨材，以替代天然砂石骨材，其資源化利用之數量巨大，可以消化疏濬之水庫淤泥。
針對水庫淤泥中細粒片狀之黏土礦物顆粒在乾燥過程中脫水不易和容易產生龜裂的特性，本研究採取在塑性黏土中掺入0 %、5 %、10 %、20 %的磚粉粉末，以擔任乾燥過程中的水氣通路和收縮間隙，不但可以增加坯體乾燥速度而且可減少坯體乾裂現象的發生。
實驗結果顯示在有添加磚粉之骨材生坯，磚粉顆粒可以增加坯體之水氣通路使得乾燥速率增加，並且提供乾燥時的收縮間隙，乾燥收縮率由5~7 % 減少至1~3 %，因此不易乾燥收縮變形。乾坯強度增加，同時使得在燒結後骨材強度也隨之提高，以MTS量測輕質骨材單顆顆粒之強度，添加10 %磚粉在600℃持溫10min、1200℃持溫2hr下燒結坯體的抗壓強度可達38MPa，其強度標準差範圍也比未添加磚粉小，證實添加磚粉混合到水庫淤泥之中可得到較高強度及品質均一的輕質骨材。

The objective of this experiment study has been aimed for understanding of the effects of addition. The dry brick powders are added to reservoir sludge mud (clay) for the preparation of lightweight aggregates. This is a mission for the recycling of the enormous deposits in the 60 reservoirs of Taiwan.
Addition of brick powders tends to promote the drying or dewatering rate of the feedstock material. Addition of brick powders is different from 0% to 20% by weight. There are two functions which are increasing the vapor passing and reducing the shrinkage clearance while the green body is drying. The mixture of the clay and brick powders is tested by drying rate, shrinkage of drying, density and strength in the extrusion, drying and sintering operations to find the formula for manufacturing of lightweight aggregates.
The strength of the lightweight aggregate product, prepared from the mixture of the clay and brick powers, is significantly affected by brick powders addition. The shrinkage clearance reduced from 7 % to 3 %. The highest strength is obtained for that with 10 wt% addition, giving 37MPa.Calcination of the green bodies was performed by a heating procedure, as: 600℃ maintaining for 10 minutes and raising the temperature to 1200℃, maintaining for 2 hours.
The addition of brick powders has the beneficial effect of promoting faster dewatering or drying rate of the green bodies of clay brick mixture. The drying rate is considered as a significant factor for medicating the characteristic of the lightweight aggregate.
