Enhanced Utilization of Coal Ash in Construction: Physicochemical Properties and Compressive Strength of Blended Cement and Geopolymer Mortar

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
The properties of fly and bottom ashes produced by Morupule power stations in Botswana are analysed for their pozzolanicity. Furthermore, the influence of physical, chemical and microstructural properties of the ashes on the performance of compressive strength of fly ash–based blended cement and geopolymer mortar was evaluated.

Low‐Carbon Concrete Systems: A Comparative Review of Binder Technologies and Alternative Materials

Journal of Engineering, Volume 2026, Issue 1, 2026.
About 8% of the world′s carbon dioxide emissions come from the production of concrete, mostly from the clinker used to make regular Portland cement. By comparing supplementary cementitious materials (SCMs), alkali‐activated materials (AAMs), alternative aggregates, and waste‐derived elements using a shared carbon‐performance paradigm, this review ...

Artificial Lightweight Aggregates Made from Pozzolanic Material: A Review on the Method, Physical and Mechanical Properties, Thermal and Microstructure

Materials, 2022
As the demand for nonrenewable natural resources, such as aggregate, is increasing worldwide, new production of artificial aggregate should be developed. Artificial lightweight aggregate can bring advantages to the construction field due to its lower density, thus reducing the dead load applied to the structural elements.

Using Pozzolanic Materials to Improve Mechanical Properties of Lime‐Based Mortar

Journal of Chemistry, Volume 2026, Issue 1, 2026.
The environmental impact associated with the production of Portland cement has intensified interest in sustainable alternatives such as lime‐based binders. However, their application is constrained by low early strength and slow hardening. This study evaluates rice husk ash (RHA) and sugarcane bagasse ash (SCBA) as pozzolanic additives to enhance the ...

Nano‐Pozzolanic Reaction Empowering Sustainable Construction with Hydrogel

Advanced Sustainable Systems, Volume 9, Issue 6, June 2025.
Nanoclay (NC) hydrogel can provide multifunctionality to building structures by chemically bonding to the surface of cement materials without the need for special adhesives or supports. This study shows that cement structures with attached NC hydrogel exhibit excellent thermal insulation effects and support successful plant growth.
