Physicochemical properties of ettringite/meta-ettringite for thermal energy storage: Review
Solar Energy Materials and Solar Cells, 2019 Abstract The cost of materials is one of main obstacles for the development of thermochemical energy storage. Compared with traditional inorganic salt hydrates, a mineral named ettringite can easily overcome this limit thanks to its large resource from cementitious materials.

Advanced Materials, Volume 38, Issue 44, 7 August 2026.Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Ettringite Seeds for Strength Enhancement: Novel Synthesis via One‐Step Co‐Precipitation
Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.ABSTRACT Reduced early strength can be a barrier to the adoption of cements blended with high levels of limestone. Chemical admixtures based on nucleation seeding are emerging as a potential solution. Herein, while synthesis of C‐S‐H‐based seeds has been thoroughly investigated in the literature, there are limited synthesis protocols available on other

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.ABSTRACT The influence of dialyzed styrene‐acrylate copolymers with similar charge, but different functional groups—carboxylate and sulfonate—on the hydration of ordinary Portland cement (OPC), alite, and a synthetic cement system was investigated. The retardation and depression mechanism by polymer particles could be clarified by combining heat flow ...

Journal of Applied Polymer Science, Volume 143, Issue 20, May 20, 2026.Surface functionalization of polypropylene macrofibers to enhance fiber‐matrix interfacial bonding. ABSTRACT Concrete is the most used higher compressive strength‐building material, albeit brittle to tensile, and flexural loads. Polypropylene (PP) synthetic polymeric macrofibres are commonly employed as reinforcement material to prevent this situation ...
