Feasibility Study On Analysis Of Dredged Mud As Building Material

Since30years of reform and opening up, China’s coastal areas rely on marine advantage made great economic achievements, but the ocean dredgeg mud accompanied with the increasingly construction and maintenance projects on the port is growing rapidly. Whether it is the traditional way to dump the ocean dredged mud or for land reclamation, both of them will give a huge negative impact on marine environment. In fact, the ocean dredged mud is an enormous valuable recycling resources. Now studying on dredged sludge resource utilization at home and abroad were achieved certain results. But unfortunately, for the limitation of immature technology there is no one be used to industrialization operation.Advocated development and use green, low carbon building materials are the key point and main target for building materials reformance described by the12th Five-Year Plan, also are important links to realise low energy consumption, light pollution and high efficiency of transformation in manufacturing industry. Developing variety and quality of recycling building materials can reduce a variety of solid waste and achieve economic and social benefits. In the current situation, realizing resources low-carbon recycling development has crucial significance on China’s future economic and social.In the context of sustainable development, this paper focus on the field of researching the offshore dredging mud resource utilization, in-depth analysis of dredging mud processing problems, and demonstrates the dredged sludge resource utilization for our country to develop the marine economy development has positive effect. Based on previous studies suggested the use of dredged mud production autoclaved brick has feasibility of implementation industrialization production. The paper has concluded the feasible of producing the brick from the dredged mud comprehensive utilization policy, environmental benefit, market prospects, technical conditions, industrial economic benefits. The feasibility study, evaluation of social benefits and economic benefits evaluation theory are used to analysis the necessity of dredged sludge resource utilization to coastal economy, ecological development constraints and the future dredged sludge resource utilization. From our country current sustainable development strategy and the view of changing the mode of economic development, the construction of resource-saving and environment-friendly development resources recycling economy is the key research direction, and legislation and policies on utilization of waste have clear instructions. Combining with other solid waste, dredging mud can be use as the main materials to produce qualified autoclaved brick. Analysis the current situation of China’s building materials marke, there is a a larger market space for dredged mud autoclaved brick that is low energy consumption, low pollution, high efficiency of wall material.Simulation building a dredged mud autoclaved brick factory to analysis of investment and benefit index shows that dredged mud autoclaved brick will produce good economic benefit.
