In this paper, magnesium oxychloride cement with stoichiometry 3Mg(OH)2∙MgCl2∙8H2O (MOC 3-1-8) was prepared and characterized. The phase composition and kinetics of formation were studied by X-ray diffraction (XRD) and Rietveld analysis of obtained diffractograms. The chemical composition was analyzed using X-ray fluorescence (XRF) and energy dispersive spectroscopy (EDS). Furthermore, scanning electron microscopy (SEM) was used to study morphology, and Fourier Transform Infrared (FT-IR) spectroscopy was also used for the analysis of the prepared sample. In addition, thermal stability was tested using simultaneous thermal analysis (STA) combined with mass spectroscopy (MS). The obtained data gave evidence of the fast formation of MOC 3-1-8, which started to precipitate rapidly. As the length of the time of ripening increased, the amount of MgO decreased, while the amount of MOC 3-1-8 increased. The fast formation of the MOC 3-1-8 phase at an ambient temperature is important for its application in the production of low-energy construction materials, which corresponds with the challenges of a sustainable building industry.

The laboratory testing of the construction materials and elements is a subset of activities inherent in sustainable building materials engineering. Two questions arise regarding test methods used: the relation between test results and material behavior in actual conditions on the one hand, and the variability of results related to uncertainty on the other. The paper presents the analysis of the results and uncertainties of the simple two independent test examples (bond strength and tensile strength) in order to demonstrate discrepancies related to the ambiguous methods of estimating uncertainty and the consequences of using test methods when method suitability for conformity assessment has not been properly verified. Examples are the basis for opening discussion on the test methods development direction, which makes possible to consider them as ‘sustainable’. The authors address the negative impact of the lack of a complete test models taking into account proceeding with an uncertainty on erroneous assessment risks. Adverse effects can be minimized by creating test methods appropriate for the test’s purpose (e.g., initial or routine tests) and handling with uncontrolled uncertainty components. Sustainable test methods should ensure a balance between widely defined tests and evaluation costs and the material’s or building’s safety, reliability, and stability.

Appropriate selection of construction materials is crucial for the success of any project. Poor choice of materials can lead to higher costs during construction, higher long-term operation and maintenance expenses, and endanger humans and their surrounding environment. Since the three pillars of sustainability cover the economic, social, and environmental aspects, adoption of sustainability principles in decision making will ensure selecting the optimum construction materials. This paper presents a generic model to utilize Fuzzy Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) principles to compare the sustainability criteria of four wall material alternatives using normalized fuzzy matrices. A case study took place in United Arab Emirates (UAE) to validate the model. Several semi-structured interviews and meetings with industry experts representing material suppliers, engineering consultants, and construction contractors took place during this research. These meetings provided six selection criteria under the three main sustainability categories, agreed-upon weight for each criteria, and evaluation of the four wall material alternatives. Results obtained from consulted experts presented Sandwich Panels as the most sustainable alternative for the case study. The developed model is generic and can be implemented on any construction project, and the alternative selection can change according to the decision-makers’ opinions and preferences.

Conceptual Study

This paper pursues to study the challenges to applied sustainable building resources in building construction and to evaluate the factors influencing the choice of construction materials with respect to the concepts of sustainability. The research purpose was accomplished in two parts; in the first part, a conceptual study to establish the reasons why sustainable building resources are restricted usage in construction, and in the second part a conceptual study on sustainable building resources and their properties. In order to encourage sustainability in design and construction, several countries have developed an understanding of sustainable development for buildings. In order to decrease the negative environmental effects of buildings, the construction industry has created sustainable building approaches, where buildings play an important role in greenhouse gases, massive energy, and water use and large land use are important. Ecological design involves designing houses, offices, or other facilities in a way that decreases the ecological impact, that means sustainable buildings, Where the careful equilibrium among economic, environmental, and social well-being of the currency and communities and therefore of the earth looks to sustainability at current. In order to evaluate the degree of sustainability practices, sustainability evaluation systems were established for effective performance at the top level of qualified systems. In sustainable buildings, accredited standards and checklists will be planned, built, and run.

Sustainable building management is a complex problem which needs effective, adequate and suitable assessment tools and methods to address issues of incommensurability and complexity, always considering the prevailing environmental policies and legislation. Within the frame of this paper, green certifications building schemes have been described, compared to each other and evaluated, against the background of the standards provided by the International Organization for Standardization. Emphasis have been placed on information referring to construction materials environmental evaluation based on the Life Cycle Analysis methodology and the role of construction materials selection to green building certification schemes. Finally, the impact of green certification schemes on the construction market, mainly as a tool of energy management, has also been examined in relation to the absence of mandatory international standardization in sustainable building management.

Sustainable Building Materials

PurposeAlthough the adverse effects of construction activities on the environment and the need for sustainable construction practices are recognised in both research and practice, any significant shift in the selection and use of construction materials from the sustainability perspective has not taken place in many building projects. Still, conventional construction materials are widely used in building projects in both developed and developing countries. This study attempts to identify the main barriers to the use of sustainable materials in building projects in an advanced economy such as Australia.Design/methodology/approachThis study adopted a questionnaire survey approach to examine the main reasons behind the low usage of sustainable materials in building projects. Based on the relative importance index, exploratory factor analysis and multinomial logistic regression analysis, the study examined the main barrier measures and barrier factors to the use of sustainable materials in building projects.FindingsThe findings reveal that critical barriers to the use of sustainable materials are related to cost and profit considerations, the unwillingness of the key stakeholders to incorporate these materials into building projects, lack of incentives and government policies. The factor analysis reduced the critical barrier measures into three factors: techno-economic considerations, cost and delay concerns and resistance to use. Furthermore, multinomial regression analysis based on the extracted factors identified techno-economic considerations as the main barrier factor to the use of sustainable materials in building projects.Practical implicationsThe empirical results of this research can inform construction practitioners, organisations and policymakers on how to increase the use of sustainable building materials in the construction industry.Originality/valueIdentification of barriers to the use of sustainable building materials is a prerequisite to improve their uptake and use in the construction industry. The study fills a gap in the existing research on the use of sustainable materials in building projects in Australia.

In this work, a prefabricated masonry element is produced by reusing a residual sludge generated by the Colombian mining industry, especially the sandstone quarries. The addition of Ca (OH) 2 and NaOH stabilizes this waste. Application of a response surface model results in optimal admixture specifications, achieving improvements in load capacity (8 MPa) and durability according to its dimensional stability, upgrading the traditional techniques. Albeit remains a lack in the study of its thermal behavior. Thus, A heat transfer analysis employing computational simulations based on the Finite Element Method (FEM) is applied to predict the thermal performance of manufactured elements with stabilized quarry sludge (SQS). Besides, several construction materials are simulated, allowing their contrast and the complement between simulation and experimentation, pointing to the achievement of a good performance in different climatic conditions, including actual city case characteristics. It is concluded that according to SQS block thermal performance, it can be a suitable building element candidate. Hence, more sustainable processes in the mining and construction production chain can be achieved.

The piezoelectric effect is extensively encountered in nature and many synthetic materials. Piezoelectric materials are capable of transforming mechanical strain and vibration energy into electrical energy. This property allows opportunities for implementing renewable and sustainable energy through power harvesting and self-sustained smart sensing in buildings. As the most common construction material, plain cement paste lacks satisfactory piezoelectricity and is not efficient at harvesting the electrical energy from the ambient vibrations of a building system. In recent years, many techniques have been proposed and applied to improve the piezoelectric capacity of cement-based composite, namely admixture incorporation and physical. The successful application of piezoelectric materials for sustainable building development not only relies on understanding the mechanism of the piezoelectric properties of various building components, but also the latest developments and implementations in the building industry. Therefore, this review systematically illustrates research efforts to develop new construction materials with high piezoelectricity and energy storage capacity. In addition, this article discusses the latest techniques for utilizing the piezoelectric materials in energy harvesters, sensors and actuators for various building systems. With advanced methods for improving the cementations piezoelectricity and applying the material piezoelectricity for different building functions, more renewable and sustainable building systems are anticipated.
