【摘要】：随着城市化进程的加快,能源的过度消耗已经成为制约社会经济发展的重要因素之一。据统计,建筑行业的能耗几乎占到社会总能耗的40%左右。因此,降低建筑能耗对于控制社会总能耗具有重要意义,这也是响应国家“节能减排”要求的一个重要举措。目前,我国使用的传统墙体材料,大多保温隔热功能较差,这将导致大量的能源耗散,不利于降低建筑能耗的要求。自保温污泥陶粒混凝土砌块作为一种新型的墙体材料,由于具备质量轻、保温隔热等优点,而受到广泛的关注。将这种新型墙体材料应用于夏热冬冷地区,不仅节能环保,而且经济适用,具有广阔的市场空间。论文对白保温污泥陶粒混凝土砌块的原材料与结构形式进行了优化设计,对其物理力学性能、耐久性能、放射性能和热工性能等进行了研究分析,具体内容如下：(1)从砌块的材料选择、块型设计(孔型、孔洞排列数、空气间层厚度等)及生产工艺等方面进行了系统的研究,设计出符合本地区建筑节能要求的自保温污泥陶粒混凝土砌块。(2)对自保温污泥陶粒混凝土砌块的相关性能进行了研究,包含块体密度、吸水率、含水率、抗压强度、软化性能、碳化性能、抗冻性能及放射性能等,并分析了各性能特征。(3)研究了自保温污泥陶粒混凝土砌块砌体的热工性能,计算了自保温污泥陶粒混凝土砌块砌体传热系数的理论值,测试了自保温污泥陶粒混凝土砌块的传热系数,并对其保温隔热性能展开研究与分析,结果显示,自保温污泥陶粒混凝土砌块符合夏热冬冷地区建筑节能的要求。(4)运用ANSYS有限元分析软件建立了有限元模型,对自保温污泥陶粒混凝土砌块的温度场进行稳态传热模拟分析计算,将模拟计算值与砌块砌体热工试验测试结果进行比较分析,验证了有限元模拟方法的可行性。(5)比较分析了自保温污泥陶粒混凝土砌块的节能百分比和投资回收期,结果表明,自保温污泥陶粒混凝土砌块具有节能效益高、经济性能好以及投资回收期短等优势。
[Abstract]:With the acceleration of urbanization, excessive consumption of energy has become one of the most important factors restricting the development of social economy. According to statistics, the energy consumption of the construction industry accounts for almost 40% of the total energy consumption. Therefore, reducing building energy consumption is of great significance to control the total energy consumption of society, which is also an important measure to meet the requirements of national "energy saving and emission reduction". At present, most of the traditional wall materials used in our country have poor insulation and insulation function, which will lead to a large amount of energy dissipation, which is not conducive to reducing the requirements of building energy consumption. As a new type of wall material, self-insulating sludge ceramic concrete block has attracted wide attention because of its advantages of light weight, heat insulation and so on. The application of this new wall material in hot summer and cold winter area not only saves energy and environmental protection, but also is economical and applicable, so it has broad market space. In this paper, the raw materials and structural forms of white insulation sludge ceramic concrete block are optimized, and its physical and mechanical properties, durability, radiation properties and thermal properties are studied and analyzed. The specific contents are as follows: (1) A systematic study has been carried out on material selection of blocks, block design (holes, number of holes arranged, thickness of air interlayer, etc.) and production process. The correlativity of self-insulating sludge ceramsite concrete block is studied, including bulk density, water absorption, moisture content, compressive strength, softening performance, etc. The carbonation property, frost resistance and radiation property are analyzed. The thermal properties of self-insulating sludge ceramic concrete block masonry are studied, and the theoretical value of heat transfer coefficient of self-insulating sludge ceramic concrete block masonry is calculated. The heat transfer coefficient of self-insulating sludge ceramsite concrete block is tested, and its thermal insulation property is studied and analyzed. The results show that, Self-insulating sludge ceramsite concrete block meets the requirement of building energy saving in hot summer and cold winter area. The finite element model is established by using ANSYS finite element analysis software, and the steady state heat transfer simulation calculation of the temperature field of self-insulating sludge ceramsite concrete block is carried out. By comparing the calculated values with the test results of block masonry thermal test, the feasibility of finite element simulation method is verified. The energy saving percentage and investment recovery period of self-insulating sludge ceramsite concrete block are compared and analyzed. The results show that, Self-insulating sludge ceramsite concrete block has the advantages of high energy saving benefit, good economic performance and short investment recovery period.
