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.

Microbial Deterioration Potential and Mitigation Strategies in Blended Cement Structures: A Review

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Microbial‐induced deterioration (MID) is a threat to the durability of cement‐based materials (CBMs) particularly in sewer and wastewater systems. Whereas blended cements incorporating supplementary cementitious materials (SCMs) offer environmental benefits such as reduced carbon (IV) oxide (CO2) emissions and enhanced mechanical performance, their ...

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.

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.
