【摘要】：工业革命以来,各国的工业发进程获得了飞跃的发展,生产力的转型与跳跃式进步,加剧了世界不可再生能源消耗量。进入到21世纪,全球的能源诸如石油、天燃气、煤的化石能源逐渐变得紧缺,这进一步引发了首先是欧美等发达国家研究人员如何更加有效合理利用与节约能源的关注。建筑砌块、保温砂浆等建筑保温材料在更全面匹配建筑墙体节能要求变得越来越严格,因此当前置于节能保温议题之首的主要是如何研发新型保温墙体材料以及促进其发展与推广。通过使用新型环保节能材料与水泥等无机粘结料有效结合,综合利用各类材料的优势性能再结合不断改进及创新的施工技术,开辟了新型墙体节能保温材料发展的新方向。本文分析和概括了目前大量应用的新型保温材料和保温技术,通过研究对比,总结出了大部分新型保温材料和保温节能工艺技术都缺乏妥善的处理热桥,导致了墙体热工性能不佳,而且大多数工艺施工速度慢,工序繁多。因此本文提出一种基于“整体现浇”工艺的胶粉聚苯颗粒现浇整体墙(下文简称CWEE),其采用胶粉水泥基粘结料、聚苯颗粒、外加剂、纤维素为主要原材料,采用全过程整体现浇,与梁柱紧密结合,有效地阻断了墙体与主体结构的热桥产生;具有良好的热工性能。针对CWEE墙体的施工工艺特点,由于没有特定的规范和标准对其加以限定,因此依据国家颁布的相关类似标准对相似材料的试验方法,对其进行试验与研究。干密度与含水率与材料的渗透性能关系密切,因此采用密度、含水率检测来分析与评价CWEE的抗渗强度,并用抗渗试验来确定影响CWEE墙体抗渗性能的因素,进而提出改善其抗渗性的措施;通过对坍落度的分析、掺水量的计算为以后施工奠定了基础;通过模板支设试验、养护方案试验来研究CWEE浆料墙体的施工操作性;并通过计算了在净自重作用下的强度贡献分析了浇筑模板偏移和挤压的必要性;详细介绍了CWEE浆料墙体自保温体系的系统构造及自保温性能;并通过中试生产与工程实践结合其带来的社会经济效益论证其推广的可行性。同时为使CWEE墙体能够更好在工程中得到运用与推广,总结了其在工程使用中的一些建议。
[Abstract]:Since the Industrial Revolution, the process of industrial development in various countries has been developed by leaps and bounds, and the transformation of productive forces and leaping progress have aggravated the world's non-renewable energy consumption. By 21th century, global energy sources such as oil and natural gas, The fossil energy of coal has gradually become scarce, which has further aroused the concern of researchers in Europe and the United States and other developed countries on how to use and save energy more effectively and reasonably. Thermal insulation materials such as thermal insulation mortar have become more and more stringent in more comprehensive matching of building wall energy conservation requirements. Therefore, at present, at the top of the topic of energy conservation and heat preservation is how to develop new insulating wall materials and promote their development and promotion. By using new environmental protection and energy saving materials and inorganic binders such as cement, they can effectively combine. By synthetically utilizing the advantages of various materials and combining with the continuous improvement and innovation of construction technology, a new direction for the development of new wall energy saving and insulation materials has been opened up. This paper analyzes and summarizes the new type of insulation materials and insulation technology which are widely used at present. Through research and comparison, it is concluded that most of the new thermal insulation materials and heat preservation and energy saving technology are lack of proper treatment heat bridge, which leads to poor thermal performance of wall, and most of the process construction speed is slow. Therefore, this paper puts forward a kind of cast-in-place integral wall based on "integral cast-in-place" technology (hereinafter referred to as CWEEN), which uses rubber cement based binder, polybenzene particle, admixture, cellulose as the main raw material. The whole process of cast-in-place is adopted, which is closely combined with Liang Zhu, which effectively blocks the generation of thermal bridge between the wall and the main structure, and has good thermal performance. According to the construction technology characteristics of CWEE wall, Because it is not limited by specific norms and standards, the similar materials are tested and studied according to similar standards promulgated by the country. The dry density and moisture content are closely related to the permeability of the materials. Therefore, the density and moisture content are used to analyze and evaluate the impermeability of CWEE, and the factors affecting the impermeability of CWEE wall are determined by impermeability test, and the measures to improve the impermeability of CWEE wall are put forward. The calculation of water content laid the foundation for the later construction, through the formwork support test, the maintenance scheme test to study the CWEE slurry wall construction operation; The necessity of pouring formwork deviation and extrusion is analyzed by calculating the strength contribution under net self-weight, and the system construction and self-insulation performance of CWEE slurry wall are introduced in detail. The feasibility of popularizing CWEE wall is demonstrated through the combination of pilot production and engineering practice. In order to make CWEE wall be better used and popularized in engineering, some suggestions in engineering application are summarized.
