Evolution of multi-scale pore structure of concrete during steam-curing process
Microporous and Mesoporous Materials, 2019Steam-curing at elevated temperature involves a complex hygrothermal coupling action, which greatly affects the hydration process, microstructure buildup and thus the mechanical and long-term properties of cement-based materials.

FRAGMENTATION IN RANDOM PORE STRUCTURES
Chemical Engineering Communications, 1989The problem of fragmentation of solid phase in reacting porous structures that consist of d (d = 1,2,3) mutually perpendicular bundles of parallel, randomly overlapping cylindrical capillaries is considered. The evolution of fragmentation with the porosity is studied using a Monte Carlo stimulation procedure which rests in using the trajectories of ...

Quick image analysis of concrete pore structure based on deep learning
Construction and Building Materials, 2019A fast image technique was proposed to characterise the pore size (>10 μm) distribution of cement-based materials based on a deep learning model. Furthermore, a dataset of concrete pore structures was established for the analysis, and a number of ...

AbstractThe effect of washing on the texture of silica gel has been investigated in terms of parameters such as porosity, pore size distribution, surface area and absorption of moisture. It was observed that if silica gel (before activation) is washed with water containing dissolved ions such as Ca and Mg wider pores are formed at the expense of ...

Influence of microstructure on process rates and product texture is widely accepted. Simulation of the pore structure of various food materials and numerous food processes has attracted recent attention in the food literature. Several approaches have been applied to predict transport phenomena in food materials.
