Journal ArticleDOI
Reactive molecular dynamics and experimental study of graphene-cement composites: Structure, dynamics and reinforcement mechanisms
TL;DR: In this article, the effects of graphene and graphene oxide on the hydration, microstructures and mechanical properties of cement paste were investigated by using reactive force field molecular dynamics (MD), revealing that functional hydroxyl groups in GO provide non-bridging oxygen (NBO) sites that accept hydrogen-bonds of interlayer water molecules in the calcium silicate hydrate (CSH).
Journal ArticleDOI
Effects of graphene oxide agglomerates on workability, hydration, microstructure and compressive strength of cement paste
TL;DR: In this article, the effects of graphene oxide (GO) agglomerates on the workability, hydration, microstructure, and compressive strength of cement paste were addressed.
Journal ArticleDOI
Incorporation of graphene oxide and silica fume into cement paste: A study of dispersion and compressive strength
Xiangyu Li,Asghar Habibnejad Korayem,Chen Yang Li,Yanming Liu,Hongsen He,Jay Sanjayan,Wenhui Duan +6 more
TL;DR: In this paper, the dispersion of graphene oxide (GO) in simulated pore solution and cement paste was investigated, and it was found that severe GO aggregation occurred in presence of divalent calcium ions.
Journal ArticleDOI
Effects of Graphene Oxide On Early-age Hydration And Electrical Resistivity Of Portland Cement Paste
Wengui Li,Wengui Li,Xiangyu Li,Xiangyu Li,Shu Jian Chen,Yan Ming Liu,Wenhui Duan,Surendra P. Shah +7 more
TL;DR: In this article, the effects of graphene oxide (GO) on the early-age hydration process and mechanical properties of Portland cement paste were experimentally investigated in a study based on an isothermal calorimeter measurement, the hydration rate of cement was observed to increase with the increase of GO content by nucleation effect.
Journal ArticleDOI
Fabrication and stability of form-stable diatomite/paraffin phase change material composites
TL;DR: In this article, three grades of diatomite particles, DP1, DP2 and DP3, were used to produce phase change material composites, DP 1P, DP 2P and DP 3P.
