The key to its planning is an ecological integration to make trade-off between economic wealth and environmental health, between material and spiritual civilization, between natural and human eco-cybernetics. Integration, demonstration, citizens’ participation and scientists’ and technician’s catalyzing are the key instruments for the implementation of the ecocity plan. "Clean production" and "ecological industry" are key elements in comprehensive development towards an eco-city. Beyond the technical and management questions, how to interlink production, consumption and reduction at the local and regional level, the spatial and urban dimension should be considered in order to perform an integrative urban eco-space.展开更多

On average 0.8 to 0.9 ton of CO<sub>2</sub> is emitted to produce one ton of OPC. In this paper, partial substitution of clinker (30% - 35%) by the calcined clay-limestone mixture was investigated in order to produce an eco-cement (LC3). Analyzes by XRF, XRD and ATG/ATD have characterized different components, determined the calcination temperature and selected the right clay which can act as effective Supplementary Cementitious Material (SCM). Mechanical tests on mortar carried out over a period of 90 days. The WBCSD/WRI “Greenhouse Gas Protocol” methodology then allowed the calculation of CO<sub>2</sub> emissions into the atmosphere. Three types of clay are available in the Songololo Region. The kaolinite is the principal clay mineral and its content varies from 27% to 34%. The sum of kaolinite and amorphous phase which enable clay to react with cementitious material ranges from 57% to 60%. The SiO<sub>2</sub> content ranges from 33% to 76%, the Alumina content from 12% to 20% so that the ratio Al<sub>2</sub>O<sub>3</sub>/SiO<sub>2</sub> is on the higher side (0.17 - 0.53). The calcination window is between 750°C and 850°C and the best clay which can act as SCM identified. The clinker’s substitution reduced CO<sub>2</sub> emissions from 0.824 ton of CO<sub>2</sub> for one ton of OPC to 0.640 ton of CO<sub>2</sub> for one ton of LC3, means 22% less emissions. The compressive strengths developed by LC3 vary from 8.91 to 57.6 MPa (Day 1 to Day 90), exceed those of references 32.5 cement and are close to 42.5 cement. In view of the results, LC3 cement can be considered for industrial trials.展开更多

In the project, the burning process and minerul compositions of CKD dinker were investigated. Different minerulizers such as CaSO4 and CaF2 , sulfur and alkali corttent were coasidered. The strength of CKD and GBFS eco-cement were evaluated. The results indicate the CKD clinker can not only form ordinary cement clinker minerals such as C3 S, C2 S and C4 AF , but also form such high-reuctive minerals as C4 A3 S and C. A7 · CaF2 . The CKD and GBFS eco-cement will have the similar strength to the Portland cement grade 32.5 when blend proportion is properly applied.展开更多

It fi rstly introduces the background, procedures and achievements gained during the green building practice in the Sino-Singapore Tianjin Eco-City, expounds the principles and methods of the establishment of the green building management system in this Tianjin Eco-City, and then focuses on practical experience and specifi c measures in separate parts of green building management system in the Tianjin EcoCity, which is constituted by laws, regulations and policies, technical standards, management process, product access, etc. Through exploration and practice, it took 8 years for the Sino-Singapore Tianjin Eco-City to preliminarily establish a set of management systems which were suited to its own characteristics. By introduction of the management system, this paper aims to provide reference for other cities to carry out green building practice and improve the quality of green buildings in China.展开更多

The entropy method and coupling coordination degree model were integrated to evaluate the coupling coordination degree between urbanization and the eco-environment in Mongolia during 2000-2016. The results showed that the coupling coordination degree between urbanization and the eco-environment in Mongolia was generally at the stage of seriously unbalanced development, and that the main contributor of the urbanization and the eco-environment subsystem were demographic urbanization and eco-environment endowment, respectively. The southern part of Mongolia central zone should be paid more attention due to the lower degree of coupling coordination between urbanization and the eco-environment. To promote the healthy urbanization development in Mongolia, six-layer eco-city establishing green development pattern is proposed to provide scientific support for Mongolia.展开更多
