碩士 === 國立聯合大學 === 建築學系碩士班 === 103 === Due to the rapid economic development and science and technology in Taiwan, increasing people's livelihood water, topography, geology and climate affect Taiwan, so the impact of reservoir sedimentation growing, and because of the rapid scientific and technological and economic development in Taiwan, increasing people's livelihood water, topography, geology and climate affect Taiwan, so the impact of the growing reservoir sedimentation and reservoir sediment deposition will result in the loss of generating capacity of the reservoir, so that the use of sludge reservoir, in the future will be an important issue in today's process Reservoir sludge disposal method mostly handled easily impact on the environment, if the sludge reservoir effective treatment resources, and with the reservoir of the dredging project. So the reservoir can reduce pollution on the ecological environment of sludge. Reservoir sediment deposition will produce loss of reservoir capacity, and therefore, the use of sludge reservoir, in the future will be an important issue in today's processing methods of reservoir sludge disposal mostly handled easily impact on the environment, if the reservoir effective sludge treatment resources, and dredging of the reservoir with. So the reservoir can reduce pollution on the ecological environment of sludge. This study is intended to reservoir sludge and gypsum, as the test structure materials, the use of chemical characteristics of the existing reservoir sludge clay of sludge bricks mixed with plaster, hope can be added through the plaster, reducing the weight of sludge brick, and then applied to the partition walls, construction should be able to take into account the nature and basic properties. In this study, Taguchi experimental method, L9 orthogonal table to join the experiment planning to add 10% to 30% of the gypsum mud bricks for their unit weight, density, water absorption and compressive strength were tested by the statistical mud brick the test results, analyze the impact of various factors arising from comparison of the development process in mud brick, brick investigate the mechanical properties and the development of basic performance benefit analysis, that analysis of the most appropriate combination of ratio, it is desirable to reduce the consumption of natural resources and environmental damage ; on the other hand expect without losing light and reduce costs under the premise of increasing the economic benefits of green building materials, and meet their needs, the value of this study is. Keywords: reservoir sludge, gypsum, brick, Taguchi experimental method.
