Molecular Dynamics Study of Water and Ions Transported during the Nanopore Calcium Silicate Phase: Case Study of Jennite
Publisher: American Society of Civil Engineers
Abstract: Durability is an important property that determines the long-term behavior of cement-based materials. Water and ions are transported in nanopores of calcium-silicate-hydrate (C-S-H) gels, the main element in cement-based ...
Assessing Interfacial Bonding Performance of PVA Fiber and Cement Hydration Products: An Atomic Simulation
Publisher: ASCE
Abstract: The composition and properties of the interface are the key points which determine the properties of fiber-reinforced cement–based composites. The bonding performance between fibers and different hydration products at the ...
Mesoscale Simulation of the Effect of pH on the Hydration Rate, Morphology, and Mechanical Performance of a Calcium-Silicate-Hydrate Gel
Publisher: ASCE
Abstract: The pH plays a key role in the hydration process of cement clinker and thus determines the morphology and mechanical performance of cement-based materials. Herein the effect of pH on the nucleation rate, morphology, and ...
Polymer Enhancement Mechanisms in Cementitious Materials: Insights from Atomistic Simulation
Publisher: ASCE
Abstract: The mechanical properties of organic/inorganic composites at a macroscopic level are largely determined by the interaction mechanisms at the interface. However, there have been limited microscopic studies on these interactions. ...
