网页In this work, COMSOL is used to model two of the most relevant phenomena that arise in concrete materials (viscoelastic creep and shrinkage) and their impact on the mechanical properties of a sensor embedded in it; in particular the simulation results of a prototypal pressure sensor embedded in concrete for Structural Health Monitoring (SHM) is ...
Molecular simulation of calcium-silicate-hydrate and its …
网页2023年12月15日 · Calcium silicate hydrate (C-S-H) is crucial in cementitious materials. Molecular dynamics simulation is an effective bottom-up approach for uncovering the origins of C-S-H strength and durability at the nanoscale level.
网页Calcium silicate is a frequently used building material with a relatively brittle fracture characteristic. Its initial E-value varies, as well as tensile strength and post peak behavior. Therefore, in the simulation, initial E-values were randomly assigned to the elements of the model and a step function used for describing the descending branch.

An approach for quantifying the calcium leaching effect on service ...
网页2023年12月1日 · Under the action of long-term environmental water, the main hydration products within the concrete matrix of the cutoff wall, such as calcium hydroxide (CH) and hydrated calcium silicate (C-S-H) gel, are easily dissolved to form Ca 2+ and are continuously leached under the combined driving effect of concentration and hydraulic gradients, i.e ...
Temperature evolution during the compaction of calcium silicate …
网页2019年6月22日 · To better understand the heat diffusion behaviour in the calcium silicate hydrate powder (PA) and compacts, COMSOL multiphysics (COMSOL Inc., Sweden) was used to simulate temperature profiles of the compression calorimeter device and the samples at different boundary conditions (t = 3, 5, 10, 20, 30 and 60 min).
