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.

Commercial plaster (CaSO4•1/2H2O) is a material used in building construction all over the world. This construction material is used renderings in internal and dry environment because it is soluble in water. According to different studies, the plaster manually applied as renderings produces high volume of material loss (values varying from 18% to 35%). In this way, the aim of this work was to study the physical and mechanical properties from pastes made with commercial plaster and pastes obtained from hydrated plaster that was lost from their applications (recycled plaster). The recycled plaster was grounded and burnt at different temperatures in order to loose its non-evaporated water and to make possible its reuse as binder. After burning, their physical and mechanical properties were studied. The results showed that recycled plaster had a good performance as binder. Their physical and mechanical properties related to commercial plaster were very similar. In this way, the results show that it is possible to reuse the recycled plaster as binder again, which permit to contribute to a sustainable construction.

This study aims to quantify the losses to third-parties on construction sites by determining the loss indicators and identifying the relationship between the losses and the indicators to improve the sustainability on building construction sites. The growing size and intricacy of recent construction projects have resulted in the growth of losses, both in quantity and frequency. Notably, third-party losses are rapidly increasing owing to the urbanization of the environment and increases in construction scale. Therefore, for efficient and sustainable construction management, a financial loss assessment model is essential to mitigate and manage such loss. This study uses the third-party losses on construction sites obtained from a major South Korean insurance company to describe the difference from the material losses and to disclose the loss indicators based on actual economic losses. ANOVA analysis and multiple regression analysis are adopted to identify the variance and define the loss indicators and to make prediction models, respectively. Several groups of loss indicators are investigated, including construction information and the occurrence of natural disasters. The findings and results of this research afford an essential guide to sustainable construction management, and they can serve as a first stage loss assessment model for construction projects.

The objective of this study was to evaluate the extent to which the practicing architects in Malaysia were familiar with timber products as a construction material. The materials consumption data was extracted from the Construction Industry Development Board (CIDB) database and was used to conduct a survey among 189 respondent architects. The results indicated that the architects were familiar with common timber products such as plywood, fiberboard, particleboard, and laminated veneer lumber. Correlation analysis of awareness and knowledge against the rate of utilization of these timber products was significant. Furthermore, the most important deterrent factors for the use of timber products in building construction in Malaysia were the high cost, poor durability, restrictive building codes and by-laws, as well as the low fire resistance. More aggressive promotion of timber products as a potential construction material is advisable to be undertaken when the goal is to boost the material’s use in the construction industry. Policy makers may also consider providing financial incentives to increase timber products utilization in building construction in Malaysia.

Buildings are essential facilities in the delivery of quality education in any nation. Providing not just buildings but sustainable ones is necessary, since educational buildings are meant to serve both the present generation, and generations to come. However, bold statements as to the poor sustainability nature of construction projects in most developing countries around the world have been made by researchers. This study therefore assessed the challenges of sustainable construction (SC) and the possible measures for mitigating the issue of poor sustainability in the Nigerian construction industry (NCI). Survey design was employed and questionnaire was administered on construction participants in selected higher institutions. Data gathered were analyzed using percentage, mean score, Kruskal-Walis H-test, and factor analysis. The study revealed that the significant challenges of SC are majorly construction related, sustainability awareness and knowledge related, finance related, and government related. To improve on the sustainability of construction projects, then strict government policy on SC, and jettisoning the traditional method of construction for innovative sustainability oriented methods, is necessary. The implication of this finding is that, the method and process of operations within the NCI does not favor the attainment of SC. Therefore, if sustainability is to be achieved, a review of construction activities and processes within the industry is necessary.
