Abstract

Currently, 40 % of CO2 emissions and energy use are attributable to the building sector. Aside from thermal insulation levels and energy requirements, primary energy consumption, CO2 reductions, and the environmentally friendly properties of the materials used are currently being considered when evaluating building sustainability and energy efficiency. Therefore, it is essential to optimize the use of ecological materials in buildings in order to make them as sustainable as feasible. Utilizing slaked lime and pumice powder as binders, nine distinct types of mortars reinforced with sheep wool fibers with comparable workability were examined. This research assessed the fresh, physico-mechanical, durability, life cycle assessment and thermal properties of restoration mortars reinforced with wool fibers and containing pumice powder in place of slaked lime at 0, 25, and 50 % replacement rates. The three percentages of wool fibers by volume that were used in this investigation were 0, 0.25 and 0.50 %. It was also investigated how well the combinations held up to high temperatures, dry shrinkage, and sorptivity. Microstructural analysis of the mixtures were made based on SEM. The findings indicated that the mixture with 50 % pumice powder and 0 %wool fibers showed the best compressive strength performance, exhibiting a strength gain of approximately 953 and 643 % in comparison to the control mixture at 28 and 90 days, respectively. The same mixture also demonstrated the lowest sorptivity and dry shrinkage, while the reference blend exhibited the lowest thermal conductivity. The mixture with 50 %PP and 0.50 %wool fibers showed the best high temperature performance.

期刊介绍: The mission of Renewable and Sustainable Energy Reviews is to disseminate the most compelling and pertinent critical insights in renewable and sustainable energy, fostering collaboration among the research community, private sector, and policy and decision makers. The journal aims to exchange challenges, solutions, innovative concepts, and technologies, contributing to sustainable development, the transition to a low-carbon future, and the attainment of emissions targets outlined by the United Nations Framework Convention on Climate Change. Renewable and Sustainable Energy Reviews publishes a diverse range of content, including review papers, original research, case studies, and analyses of new technologies, all featuring a substantial review component such as critique, comparison, or analysis. Introducing a distinctive paper type, Expert Insights, the journal presents commissioned mini-reviews authored by field leaders, addressing topics of significant interest. Case studies undergo consideration only if they showcase the work's applicability to other regions or contribute valuable insights to the broader field of renewable and sustainable energy. Notably, a bibliographic or literature review lacking critical analysis is deemed unsuitable for publication.
