Sustainable concrete is nowadays one of the biggest challenges in the construction industry. Performance-based specifications for concrete can materially help meet this new challenge while supporting the concept of “sustainable construction”. Concrete can be found in almost every building structure, be it a pavement, a bridge, a house, a tunnel or a dam. Scholars nowadays are researching the best balanced mix in concrete in order to diminish its environmental impact, especially the cement component which is known for its high carbon emissions. This paper describes concrete durability and outlines what project specifications will significantly influence concrete performance, including its environmental impacts. The paper argues that, despite the sustainability of concrete, concerted efforts on the part of scientists and engineers are still necessary to improve the design of concrete in order to ensure their expected sustainable quality and reliability.

Construction industry is seen to be able to play a bigger role into a sustainable society by offering sustainable construction. As the premier construction material across the world, concrete has a major determining role on the effects, good or bad, of construction on the environment, meanwhile the formwork system is one of the important construction methods in building construction, which eventually will lead to more sustainable construction. In this context, this study focuses on the importance of the formwork system and its influence on achieving sustainable construction. The study aims to identify the basic sustainability objectives that considered responsive to formwork system. Using questionnaire survey distributed among construction experts, the economic category had been selected as the most important factor that considered respond to the formwork system, and the environmental category comes second while social comes the third. Furthermore, fifty percent of the respondents agree that type of formwork system effect on the sustainability of the construction project and about forty percent was moderate about it. Determination the objectives of sustainability that respond to the formwork system, which covers all activities and processes related to the formwork system can assist developers and others stakeholders to evaluate the performance of the system in order to make enhancement to the system.

The concept of sustainability has been growing for many years. In parallel to this popularity, the use of sustainable materials in the construction industry has increased significantly. Sustainable construction materials should be proposed and introduced to the construction industry, mostly as a replacement for cement. Cement is one of the most commonly used construction materials, which produces very high carbon emissions. As the most widely used building material in the world, concrete is predominantly comprised of cement. Therefore, sustainable alternative constituents to cement are required. This study focuses on alternative materials to cement and additionally, alternative materials to naturally available aggregates. The physical, chemical characteristics and mineralogical properties of the proposed materials are investigated and the results are demonstrated in this research study. The findings highlight the environmental and economic potential of replacing cement and other binding materials with steel slag.

The construction industry is responsible for causing a large adverse impact on the environment. To minimize these impacts, sustainable practices are being sought mainly in the area of the wastage of and the waste from raw materials. Many obstacles and difficulties are encountered when trying to implement sustainable practices in civil construction. Thus, a study to identify what the obstacles are to implementing such practices is necessary. Therefore, the objective of this study is to present an assessment of the main obstacles to implementing sustainability in civil construction for which the bow-tie tool is used. Three cases were analyzed: construction material waste, the wastage of plaster and planning a sustainable construction project. Results showed that the lack of planning for sustainable construction projects, the lack of compliance with technical standards and the lack of technical knowledge of the workforce and of standardization are among the main obstacles to implementing sustainability in civil construction. This study offers a structured methodology to identify causes, consequences and obstacles related to events that affect the implementation of sustainable practices. It provides a visualization of the scenario investigated through the diagram generated, facilitating its understanding and analysis.

Due to the great negative impact, the construction industry needs to undergo a paradigm shift from traditional construction to sustainable construction. To reach the goal of sustainable development, the construction industry needs to intensify its efforts to move to a knowledge intensive mode. Based on the analysis of e-Cognos and the concept of ontology, this paper proposes that e-Cognos ontology can be applied in the development of sustainable construction process ontology, which is a key part of knowledge management system (KMS). Following this, the application process of ontology-based KMS is analyzed using IDEF0 modeling method. Finally, this paper analyzes interorganizational collaboration model in sustainable project.

Chinese government has announced to the world that, the carbon emission will decrease by 40-45% in 2020, after the World Climate Summit in 2009. To ensure people’s living quality, while limit the green house gas emission, the construction industry - a big energy consumer - must endeavor to explore new construction method, research and develop new construction material and use new energy structure to make our promise come true.

The construction industry consumes a substantial amount of raw materials in its processes and the output is obviously the product and most importantly the waste material. Other than that, the construction industry is well known as one of the worst environmental polluters. This study is to determine the use of waste minimisation technique in creating sustainable waste management in order to identify the technique which has the most capabilities to reduce on-site waste. The objective of this study is to assess the waste minimization techniques taken from the 4R concept (which includes reduce, reuse, recycle and recovery techniques) in minimizing the waste in construction waste management. The most used waste minimization technique found in the 4R concept would be waste reduction. This shows that the local construction industry has the knowledge necessary to plan out the waste management processes but the implementation is still far from satisfying. Additionally, the findings reveal that because the industry is profit-driven, construction practitioners are motivated by profit to adapt to this techniques.
