Hydration Behavior of Tricalcium Silicate in Seawater Relevant Salt Systems: A Hybrid Study with the Aid of Machine Learning

open access: yesAdvanced Intelligent Discovery, EarlyView.
The hydration behavior of C3S in seawater‐relevant solutions is studied based on experiments, boundary nucleation and growth (BNG) modeling, and machine learning. The main ions included in seawater modify hydration mechanisms, with MgCl2 showing the strongest acceleration effect at the same concentration.

Effective Interactions between Calcium-Silicate-Hydrate Nanolayers

open access: yes, 2019
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.

Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

open access: yesThe Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

Nacre‐inspired layered composite with excellent mechanical support and osteogenic potential for cervical interbody cage

open access: yesBMEMat, EarlyView.
The cervical interbody cage needs to take both biomechanical and biological requirements into account. Here, a new‐style degradable, multicomponent, and bioinspired nacre‐like cervical interbody cage composite, which exhibits promising mechanical‐support‐related behavior and osteogenesis‐related potential, is designed and prepared.

Dehydration Process of Calcium Silicate Hydrate during Heating in the Air

open access: yes, 2011
Investigation on the continuous dehydration process of calcium silicate hydrate with C/S 1.5 during heating in the air was carried out. Results showed that the heating at 200°C of C-S-H resulted in decreasing basal spacing from 1.2 nm to 1.0 nm, and the ...
