Using molecular dynamics simulations, we investigate the influence of microwave irradiation on the nucleation and growth of Calcium\u2013Alumino\u2013Silicate\u2013Hydrate (C\u2013A\u2013S\u2013H) gels. The results show that alternating electric fields\u2500applied via intermittent (IM) or sinusoidal (SM) modes\u2500induce intense rotational and translational motion in polar water and hydroxyl groups. The alternating electric field reduces the hydrogen bond retention ratio from 0.915 in the Control group to 0.827 under SM mode and 0.725 under IM mode. Cage-jump dynamics analysis confirms the resulting \u201cdecaging\u201d of monomers, with the non-Gaussian parameter \u03b12(t) rising from 0.33 (Control) to 0.64 (SM) and 0.85 (IM), while the cage residence time \u03c4_cage decreases from 85 ps (Control) to 52 ps (SM) and 38 ps (IM). The released monomers exhibit significantly enhanced mobility, with mean square displacements increasing by 37% under SM mode and 44% under IM mode compared to the Control group.The two microwave modes drive distinct polymerization pathways. The SM mode promotes deep cross-linking into Q3 (7.0%) and Q4 (2.4%) structures through continuous energy input. The IM mode accelerates Q0 consumption (from 75% to 60%) and preferentially forms Q1 (20.2%) and Q2 (16.9%) chain-like oligomers through pulsed energy delivery. Correspondingly, Si\u2013O\u2013Si and Si\u2013O\u2013Al bond counts increase by 91.2% and 145.4% under SM mode, and by 128.6% and 294.5% under IM mode, respectively. These findings establish a fundamental link between electromagnetic energy input and nanoscale gel assembly, providing a molecular-level rationale for the accelerated strength gain observed in microwave-cured cementitious materials.<\/jats:p>","DOI":"10.1021\/acsomega.6c04884","type":"journal-article","created":{"date-parts":[[2026,9,24]],"date-time":"2026-09-24T22:02:29Z","timestamp":1790287349000},"page":"59154-59167","source":"Crossref","is-referenced-by-count":0,"title":["From Hydrogen Bond\nDisruption to Accelerated Polymerization:\nAtomic Mechanisms of Microwave-Accelerated C\u2013A\u2013S\u2013H\nGel Formation"],"prefix":"10.1021","volume":"11","author":[{"given":"Luyao","family":"Duan","sequence":"first","affiliation":[{"name":"Hebei University of Technology , , ,","place":["Tianjin, China, 300401"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruochen","family":"Zhang","sequence":"additional","affiliation":[{"name":"Hebei University of Technology , , ,","place":["Tianjin, China, 300401"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3389-4656","authenticated-orcid":true,"given":"Zhu","family":"Pan","sequence":"additional","affiliation":[{"name":"Hebei University of Technology , , ,","place":["Tianjin, China, 300401"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guowei","family":"Ma","sequence":"additional","affiliation":[{"name":"Hebei University of Technology , , ,","place":["Tianjin, China, 300401"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,24]]},"reference":[{"key":"2026100610471196500_cit1","doi-asserted-by":"publisher","first-page":"2","DOI":"10.1016\/j.cemconres.2018.03.015","article-title":"Eco-efficient cements: Potential\neconomically viable solutions for a low-CO2 cement-based\nmaterials industry","volume":"114","author":"Scrivener","year":"2018","journal-title":"Cem.
