A molecular dynamics study of cementitious calcium silicate hydrate (C-S-H) gels [PDF]
In this article we study the polymerization of silicic acids (Si(OH)4) in the presence of calcium ions by molecular dynamics simulations. We focus on the formation and structure of cementitious calcium silicate hydrate (C-S-H) gels.

Synthesis of Calcium Silicate Hydrate in Highly Alkaline System
Synthesis of calcium silicate hydrate (C-S-H) was conducted over the range of 50 degrees C-90 degrees C and C/S ratio of 0.86-2.14 in the highly alkaline Na2O-CaO-SiO2-H2O system for silicon utilization in high alumina fly ash. Structural change in C-S-

Large-scale simulation of calcium silicate hydrate by molecular dynamics
As the most important binding phase of cement paste, calcium silicate hydrate can determine the mechanical properties of cementitious materials. Structural, dynamic and mechanical properties of calcium silicate hydrate gel at the colloid level (∼15 nm ...

A nanounit‐assembled hydrogel employing a “pull‐and‐push” strategy simultaneously scavenges pro‐inflammatory cell‐free DNA (cfDNA) and delivers regenerative therapeutics in response to burn‐induced hyperthermia. By repolarizing macrophages and promoting angiogenesis, this multifunctional platform accelerates burn wound healing, offering a blueprint for

Effective Interactions between Calcium-Silicate-Hydrate Nanolayers
Calcium-silicate-hydrate (C-S-H), the main binding phase in cementitious materials, possesses a complex multiscale porous texture where nanosized particles interact effectively and contribute to the macroscopic properties of concrete.

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.

The nanostructure and degradation of C-S-H in Portland and blended cements [PDF]
The microstructure and composition of water and KOH activated hardened pastes of commercial neat white Portland cement (WPC) and blends with 30% fly ash (PFA) have been characterised using a multi-technique approach, With particular emphasis on the ...

The Atomic-Level Structure of Cementitious Calcium Silicate Hydrate [PDF]
Efforts to tune the bulk physical properties of concrete are hindered by a lack of knowledge related to the atomic-level structure and growth of calcium silicate hydrate phases, which form about 50-60% by volume of cement paste.
