Hydration, shrinkage, pore structure and fractal dimension of silica fume modified low heat Portland cement-based materials

, 2021
Low heat Portland (LHP) cement has been widely used in hydraulic projects in China, while the relatively low early strength limits its further application in engineering.

The influence of long-time water intrusion on the mineral and pore structure of coal

, 2021
The formation water intruding into the coal seam through cross-layer seriously reduces the gas extraction efficiency. In this work, a series of experiments were carried out to investigate the influence of long-time pressure water on the mineral content ...

Three-dimensional fractal characteristics of soil pore structure and their relationships with hydraulic parameters in biochar-amended saline soil

, 2021
Due to poor soil quality, coastal saline soil limits soil productivity. Therefore, it is of great importance to find appropriate and efficient methods to improve the quality of coastal saline soil.

Nanoscale pore structure and mechanical property analysis of coal: An insight combining AFM and SEM images

, 2020
Scanning Electron Microscopy (SEM) and Atomic Force Microscope (AFM), two easily acquired and widely applied image acquisition and analysis methods, have rarely been combined to study the pore structure for unconventional natural gas reservoir rocks.

Fractal characteristics of pore structure of hybrid Basalt–Polypropylene fibre-reinforced concrete

Cement & Concrete Composites, 2020
The pore characteristics of hybrid basalt–polypropylene fibre-reinforced concrete (HBPRC) are investigated using mercury intrusion porosimetry. The research results indicate that the cumulative pore volume of concrete increases with fibre addition.
