Abstract: The objective of this paper is to present a procedure which combine three reservoir sediments with industrial sludge ash to produce sintered bricks. Three reservoir sediments from southern Taiwan, Tsengwen Reservoir Sediment (TWR sediment), Baihe Reservoir sediment (BHR sediment) and Agongdian Reservoir sediment (AGDR sediment) were chosen to completely replace traditional clay as cohesive materials. This study tried to find the optimal proportion between three reservoir sediments, industrial sludge ash (ISA) and waste glass powder (WG) in manufacturing sintered bricks. For sintered bricks, loss on ignition test, fire shrinkage test, water absorption test, compressive strength test, density test and water-soluble chloride ion content test will be conducted to estimate the engineering application potential and the degree of environmental impact. The research was separated into three stages. Particle sizes, molding pressure and sintering indexes were all fixed.For the first stage, we established the feasibility and the differences of using these three kinds of reservoir sediments as substitutional material of clay. In this stage, we completely replaced the brick clay with sediments. The results all met the CNS criteria of compressive strength and water absorption rate. We also notice that higher the proportion of the particle whose diameter is smaller than 0.002 mm is, better the compressive strength becomes. We compared the three sediments and found out that BHR sediment has the best outcome.For the second stage, the 40% of sediment, 30% of ISA and 30% of WG proportion was used. However, the result compressive strength and water absorption didn’t meet any CNS criteria no matter which sediment was chosen. In this case, we decided to decrease the proportion of sludge ash by 10% in stage three. In the stage three, 50% of sediment, 20% of sludge ash and 30% of waste glass (WG) proportion was used. Although the water absorption rate still didn’t meet the lowest criteria in CNS, the compressive strengths were improved to the CNS 2nd-class level.
