Wood Ash as Sustainable Alternative Raw Material for the Production of Concrete—A Review

et al. 2023

View full text Add to dashboard Cite

Different ecological binders have been used to minimize the negative effects of cement production and use on the environment. Wood ash is one of these alternative binders, and there has been increasing research related to this topic recently. The wood ash utilized in the literature primarily originates from power plants and local bakeries, and predominantly wood fly ash is used. This review paper examines the use of wood ash as an ecological binder in two different applications: as a cement replacement and as an alkali-activated material. Studies have shown that while increased wood ash content in concrete and mortars can have negative effects on strength and durability, it is still a promising and developable material. Depending on the chemical composition of the wood ash, the strength and durability properties of concrete might be slightly improved by utilizing wood ash as a replacement for cement, with an optimal replacement level of 10–20%. However, there is a need for more research regarding the effects of wood ash on the durability of cement-based materials and its use in alkali-activated materials. Overall, this review provides a comprehensive overview of the properties of wood ash and its potential applications in conventional concrete and mortars, as well as in alkali-activated materials.

“…The US Green Building Council [77] defined green buildings as an effort to provide a comfortable living experience and reduce the damage to the ecology and environment in their entire lifecycle. The EPA [78][79][80] stated that a "green building is the practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout." Besides the abovementioned concepts, the Singapore Green Building Council (SGBC) stated that the concept of green buildings should include education enhancement, job creation, community improvement, and health protection [81].…”

In the 21st century, traditional construction activities exert a severe negative influence on the environment and ecology. To mitigate the negative influence of construction, green buildings have received increasing attention worldwide. Compared with conventional buildings, green buildings have significant advantages for environmental conservation and public health. Although green buildings bring excellent benefits, the development status of green buildings in China is still unsatisfactory. To enhance the understanding of green buildings and promote green building development in China, this study was undertaken to conduct a systematic review of green building development in China. The PRISMA protocol was used as the primary procedure for article screening and selection. This review was conducted between March 2022 and May 2022. In this study, 186 articles were reviewed, and the definition, development trends, evaluation standards, importance, and hindrances of green buildings in China were summarized and discussed through the systematic review. Moreover, the benefits, challenges, and future directions of green building promotion and development in China were discussed and analyzed. This study can promote public familiarity with the current situation of green buildings in China to boost their development. In addition, this study can also provide practical advice to green building stakeholders on the future direction of green building development in China.

“…The application of WTS in industrial processes and building materials hs become preferable due to its availability as a raw material and its wide potential (De Carvalho Gomes et al 2019). Currently, many studies have been performed using WTS in ceramic products, especially partial replacement of clay on fired bricks (Benlalla et al 2015;Erdogmus et al 2021;Amin et al 2022;Harja et al 2022). Furthermore, some attempts have been also made to utilize WTS as aggregates for cement-based composites (de Oliveira Andrade et al 2018;Chen et al 2022).…”

Water treatment sludge (WTS) is produced daily and disposed of as hazardous material. It would be advisable to use locally available waste products as supplementary cementitious materials that ensure to be disposed of without harming the environment. As a novelty, this research investigated the potential of using recycled WTS with fly ash (FA) and ground-granulated blast furnace slag (BFS) as ternary blended binders. Thus, it can provide an economical solution and alleviate the adverse environmental effects of excessive production of wastes and cement production. Within this scope, the mortars with 0–30 wt% replacement of cement with modified WTS (MWTS) were produced as binary blend, and also, they were combined with FA/BFS as ternary blended binders. Therefore, optimum utilization of waste products into the mortar in terms of rheological, mechanical, durability, microstructural properties, and environmental-economical aspects was examined. Adding 10% recycled WTS as binary caused higher strengths with lower porosity measured by the mercury intrusion porosimeter test and denser microstructure, as revealed by XRD patterns and SEM results. However, the drawbacks of using recycled WTS, in terms of rheological parameters and environmental-economical aspects, were suppressed by adding FA/BFS with comparable strength values. Specifically, cost, CO2 footprint, and embodied energy were reduced by combining 10% MWTS with FA by 8.87%, 37.88%, and 33.07%, respectively, while 90-day compressive and flexural strength were 5.1% and 5.32% lower. This study developed a feasible solution to use recycled MWTS by obtaining more eco-friendly and cost-effective cement-based materials. Graphical Abstract
