The Performance Study And Economic Benefit Analysis For Green Energy-saving Wall Materials-desulfurization Gypsum Masonry

In government advocating renewable utilization of resources and under the situation of the green building development, in order to adapt to the development trend of China's building energy efficiency, satisfy people's requirement for residential building comfort, this paper studies a new type of wall materials, desulfurization gypsum block wall, the paper studied the physical performance index and economic benefit. New desulfurization gypsum block is power plant waste desulfurization gypsum as raw material, the desulfurization gypsum, cement, fly ash and polystyrene particles according to certain proportion mixing, add new admixture, by mold molding, natural curing make into blocks. This paper, by using theoretical analysis and experimental research method of combining the research of new desulfurization gypsum block wall heat preservation and heat insulation, sound insulation performance, fire prevention performance, study it as the basic properties of the green energy-saving wall materials.Through comprehensive analysis of the economic benefits of desulfurization gypsum block, the block of production costs, construction costs in the wall and the wall in the process of using economic benefits. Based on the new desulfurization gypsum block wall performance and economic benefit analysis, for the market promotion of desulfurization gypsum block wall materials provide certain theoretical basis.This article mainly from the following several aspects to green energy-saving wall material of desulfurization gypsum block wall to explore and research:(1) Combined the modern green wall materials in building marketwith the problems existing in the development process, analysis the current market demand for wall materials, analyzed development status of green wall materials at home and abroad,the study of desulfurization gypsum block are the necessity and significanceof performance index;(2) Research on green energy-saving wall materials desulfurization gypsum block wall of sound insulation performance.The sound insulation performance of walls to make use of mass law theory research, through the laboratory test on the experimental study of the sound insulation performance of the wall, and comparison between the two aspects of research the sound insulation performance of accurate analysis of desulfurization gypsum block wall;(3) Research on wall fireproof performance.Wall of the fire prevention performance relates to the structure of the use of safety and property safety of the people.This paper mainly through the desulfurization gypsum block combustion performance test and desulfurization gypsum block wall refractory performance test to analysis the wall of the fire prevention performance;(4) Research on the thermal performance of the wall.Wall mainly from the thermal performance of the wall insulation and wall of the two sides of the insulation performance.Value of desulfurization gypsum block is the determination of the research of desulfurization gypsum block wall thermal resistance, further study on the wall heat transfer coefficient, through the several aspects study the wall heat preservation performance.Wall heat insulation performance mainly through wall thermal inertia index analysis;(5) The economic benefits of desulfurization gypsum block are analyzed.The economic benefits of wall body mainly through the analysis of the cost of production of block, wall construction cost as well as the wall using the costs and benefits, in the process of the research of desulfurization gypsum block wall in economic performance advantage;(6) Case analysis. Take the new desulfurization gypsum block wall used in HuaQing creative industrial park as an example, analysist he application situation of the new desulfurization gypsum block wall in building and good performance of the wall materials and the economic benefit brought by the good performance.
