The advancement of eco-friendly technology in the construction sector has been improving rapidly last few years. As a result, multiple building materials were developed, enhanced, and proposed as replacements for some traditional materials. One notable example presents geopolymer substitute ordinary Portland concrete (OPC). manufacturing process (OPC) generates CO2 emissions high energy demand, both which contribute to ozone depletion global warming. implementation (GPC) provides path more sustainable growth cleaner environment. This is due concrete's ability reduce environmental pollutants industry's carbon footprint. achieved through its unique composition, typically involves industrial byproducts like fly ash or slag. These materials, rich silicon aluminum, react with alkaline solutions form binding gel, bypassing need high-energy clinker production required OPC. use such not only reduces but also contributes waste minimization. Additionally, offers extra advantages compared OPC, including improved mechanical strength, enhanced durability, good stability acidic settings. Such properties make GPC particularly suitable range environments, from applications infrastructure projects exposed harsh conditions. paper comprehensively reviews different characteristics geopolymers, include their compressive curing methods. Furthermore, impacts related evaluated life-cycle assessment method. result demonstrated that maintains positive fact it produces fewer dioxide OPC during manufacturing; however, had minor negative impacts, abiotic depletion, human toxicity, freshwater ecotoxicity, terrestrial acidification. are important considerations ongoing research aimed at further sustainability concrete. Moreover, was determined silicate content, temperature, proportion solution binder major factors significantly influencing strength represents just stride toward practices paves way innovative approaches field

A Study of Modern Eco-Friendly Composite (Geopolymer) Based on Blast Furnace Slag Compared to Conventional Concrete Using the Life Cycle Assessment Approach

Infrastructures, Journal Year: 2023, Volume and Issue: 8(3), P. 58 - 58

Published: March 19, 2023

By posing the question of what will be definition sustainable development in future, it can almost seen that principle “no waste” and production new materials with less a negative environmental impact have high priority. To further develop environmentally friendly materials, is necessary to know about drivers as well evaluate effects conventional construction. According definitions characteristics such having low energy consumption, sufficient durability, good physical chemical properties, while simultaneously reducing pollution should used. Geopolymer may reasonable option. In this research, two processes based on blast furnace slag ordinary concrete (Portland cement) for one cubic meter geopolymer been investigated. investigate, inputs (materials energy) outputs (relevant pollutants) both systems were determined life cycle assessment (LCA) was measured using Center Environmental Science Leiden University (CML) cumulative exergy demand (CED) quantification methods SimaPro V.9 software. The results showed system has maximum all classes except destruction ozone layer, producing much than normal system. It also consumes 62% directly during its lifetime. As result, suitable alternative traditional material.

Effect of Combined Different Sources of Alumina Silicate on Mechanical Properties and Carbonation Depth of Environmentally Friendly Geopolymeric Composite Based on Metakaolin

International Journal of Engineering, Journal Year: 2023, Volume and Issue: 36(7), P. 1383 - 1397

Published: Jan. 1, 2023

Today, concrete is the most widely used building material. Cement production releases about 7% of carbon dioxide gas into atmosphere and increases greenhouse gases, so it seems necessary to use an alternative Portland cement. In recent years, geopolymers (mineral polymers) have been proposed as a new environmentally friendly Metakaolin, bentonite, zeolite, iron blast furnace slag fly ash can be mentioned aluminosilicate sources. field geopolymer construction, few articles working on composition effect replacing this experimental study, sources, class F bentonite with proportions 5-45% metakaolin mechanical properties durability based was investigated. After making samples, compressive, bending, tensile carbonation tests were performed samples obtain optimal strength depth samples. Also, determine validity tests, machine learning estimation analysis The findings showed that leads decrease in strength, while lead increase strength. predicted R2 values highest matching correlation matrix (more than 93%) for pressure addition, results metakaolin-based sample replaced (35%) had lower penetration (carbonation) higher other
