Nano‐Pozzolanic Reaction Empowering Sustainable Construction with Hydrogel

open access: yesAdvanced 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.

Steel Slag as Sand Replacement in Concrete: A Systematic Review of Fresh, Mechanical, and Durability Properties

open access: yesAdvances in Civil Engineering, Volume 2025, Issue 1, 2025.
The sand crisis has received growing attention in recent years, and a number of substitutes have been examined by researchers in order to reduce the use of river sand. Typical substitutes are industrial by‐products that would otherwise require land for waste disposal. Steel slag (SS) is one such by‐product that can be used as a replacement for alluvial
