Abstract Lightweight strain‐hardening ultra‐high‐performance concrete composite (SH‐UHPC) is an outstanding alternative for engineering applications and infrastructure thanks to its outstanding strength, toughness, ductility, and low density. The integration of artificial intelligence (AI)‐based modeling strategies into engineering problems can ...

ABSTRACT Workability control of alkali‐activated binders (AABs) remains an obstacle to producing low‐carbon clinkerless ultra‐high‐performance concrete, as their formulation usually necessitates low water‐to‐binder (W/B) ratios, high binder content, and concentrated activator solutions. To address this challenge, a greener and more manageable composite

Ettringite Seeds for Strength Enhancement: Novel Synthesis via One‐Step Co‐Precipitation
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

Metasurface Enhanced Photothermal Cement Foam for Robust and High‐Throughput Seawater Desalination
Schematic of 3D metasurface‐enhanced cement foam for robust and high‐throughput seawater desalination. This study presents a cement‐based solar evaporator (CSE) fabricated in one step via viscoelastic lithography with simple negative pressure. In addition to boosting solar‐to‐vapor conversion efficiency via excellent light‐harvesting capacity, the ...

Efficacy of Available Superplasticizers on Geopolymers
Geopolymer is a novel engineering binder with lower environmental impacts (CO 2 emission, embodied energy and global warming potential) than Ordinary Portland Cement (OPC). Geopolymers can be synthesized from mixing high alkaline activators by industrial by-products such as fly ash and slag as the aluminosilicate source materials.
