Published: March 1, 2024

As a common industrial solid waste, fly ash requires proper processing and utilization to alleviate environmental pressure. In contrast earlier low-value treatment methods for ash, such as its use in construction materials, it is more practical explore the high-value of considering elemental ingredient morphological characteristics. Herein, this work comprehensively reviews research progress extracting preparing silica, alumina, zeolite respectively derived from silicon aluminum elements ash. Specifically, mechanisms processes various are elucidated detail, virtues drawbacks production technologies compared identify economical environmentally friendly method. Importantly, first energy storage electrode materials. Different synthesis strategies thoroughly examined, especially fully utilizing primary resource, converting into Finally, paper summarizes opportunities challenges associated with

Microstructural attributes and physiochemical behaviours of concrete incorporating various synthetic textile and cardboard fibres: A comparative review

Journal of Building Engineering, Journal Year: 2024, Volume and Issue: 86, P. 108690 - 108690

Published: Feb. 6, 2024

The excessive use of virgin materials for manufacturing cementitious in the building and construction industry creates detrimental environmental effects. integration waste composites promote sustainable opportunities within industry. This paper presents a systematic review synthetic textile cardboard fibres concrete conjunction with infrequently used additives such as gypsum, metakaolin, alumina zinc oxide. nature polyester nylon facilitates their into high alkaline environments. Kraft fibres, derived from cardboard, exhibit tensile strength but also absorb water, limiting construction. However, by employing coating applications, these limitations can be mitigated. Gypsum prolongs setting times, improves workability, enhances sulphate resistance concrete. Metakaolin's reactivity calcium hydroxide results improved strength, density, durability. Alumina oxide enhance mechanical thermal characteristics. Whereas oxide, known its UV protection antimicrobial properties has retarder effect improve longevity extreme Scanning electron microscope images demonstrate sustained durability features composite whereas, kraft exhibited deterioration properties. Fibre bonding aspects material varied each matrix environment. corresponded to microstructural response fibrous materials. findings this sustainability when integrating additive designs.

Characterization and Applications of Red Mud, an Aluminum Industry Waste Material, in the Construction and Building Industries, as well as Catalysis

The Chemical Record, Journal Year: 2023, Volume and Issue: 23(5)

Published: April 20, 2023

The disposal of red mud (RM), a waste material generated by the aluminum industry, remains global environmental concern because its high alkalinity and smaller particle size, which have potential to pollute air, soil, water. Recently, efforts been made develop strategy for reusing industrial byproducts, such as RM, turning into value-added products. use RM (i) supplementary cementitious construction building materials, cement, concrete, bricks, ceramics, geopolymers, (ii) catalyst is discussed in this review. Furthermore, physical, chemical, mineralogical, structural, thermal properties well impact, are also It possible conclude that using catalysis, industries most efficient way recycle byproduct on large scale. However, low can be attributed reduction fresh mechanical composites incorporating RM. On other hand, used an active synthesize organic molecules reduce air pollution, not only makes solid but lowers price catalyst. review provides basic information characterization suitability various applications, paving more advanced research sustainable waste. Future perspectives utilization addressed.
