【摘要】：随着建筑业的迅速发展，由建筑业产生的建筑垃圾也空前增加，巨量的建筑垃圾除处理费用相当惊人外，且由此引发的环境问题和社会公害也很多。再生混凝土是一种以再生骨料、工业废料为主要原材料配制的植生型混凝土。这种混凝土一方面解决了大量混凝土废弃物处理困难和由此引发的对环境的负面影响等问题，同时又节省了大量的垃圾清运费用和处理费用；另一方面可以减少对天然砂石的开采，，保护了生态环境，保护了人类社会的可持续发展；再生混凝土完全满足世界环境组织提出的“绿色”的三大含义：(l)节约资源、能源；(2)不破坏环境，更应有利于环境；(3)可持续发展，既可满足当代人的需求，又不危害后代人满足其需要的能力。因此，它是一种可持续发展的“绿色混凝土”，同时混凝土生产及施工技术必须向大量节约资源、能源、减轻地球环境负荷及维护生态平衡的具有最新、最高技术水平生产经营方式发展，走可持续发展的道路，而绿色生态混凝土的研究正代表了这一最新的发展方向。本文主要利用再生骨料配制绿色生态混凝土，使其具有高有效空隙率、高强度、低碱度、高利废率和良好的耐久性能，主要研究内容是：研究绿色生态混凝土有效空隙率、抗压强度、碱环境及耐久性等性能的影响因素并确定最佳的配合比；研究选择既能适合生态混凝土植被生长要求，又能适应本地区特点的植物；研究设计适合不同工程应用的种植构造，并配制相应的营养土浆；研究施工工艺并将绿色生态混凝土应用于实际工程中以验证工程应用的可行性。
[Abstract]:With the rapid development of the construction industry, construction waste from building industry also increase rapidly, in addition to a huge amount of construction waste treatment costs quite amazing, and the resulting environmental problems and social hazards. A lot of recycled concrete is a kind of recycled aggregate, industrial waste as the main raw material preparation plant type concrete. This on the one hand to solve the problem of a large number of concrete concrete waste treatment difficulties and the resulting negative impact on the environment, but also save a lot of garbage removal costs and processing costs; on the other hand can reduce the exploitation of natural stone and sand, protect the ecological environment, the protection of the sustainable development of human society; the recycled concrete can meet the proposed world environmental organization "green" three meanings: (L) save resources and energy; (2) without damaging the environment, more conducive to the sustainable development of the environment; (3) The exhibition, which can meet the needs of contemporary people, and not to harm the ability of future generations to meet their own needs. Therefore, it is a kind of sustainable development of "green concrete", at the same time, concrete production and construction technology must be to save a lot of resources and energy, reduce the earth environment load and the maintenance of ecological balance with the latest development. The highest technical level of production and management, and take the road of sustainable development, and the research of green ecological concrete represents the latest development direction.
This paper mainly use the reclaimed aggregate green ecological concrete, which has high effective porosity, high strength, low alkalinity, high utilization of waste and good durability, the main research contents are: the research of green ecological concrete effective porosity, compressive strength, impact resistance and alkali environment factors for resistance and identify the best mix; suitable selection of ecological concrete vegetation growth requirements, and can adapt to the local characteristics of the plant; planting structure design for different engineering applications, and the preparation of the corresponding nutrient soil slurry; research on construction technology and green ecological concrete used in practical engineering to verify the feasibility of engineering application.
