Nature gas hydrates are only stable at low temperatures and high pressures; consequently,
the hydration heat of cement slurry can easily decompose hydrates. Therefore, low-heat …

In recent years, the deterioration of traffic safety due to high road temperatures and the
increase in transport costs have led to an urgent need for road users to reduce the …

This study aims to develop volume-stabilized grouts made of ordinary Portland cement
(OPC)-calcium sulfoaluminate (CSA) cement-calcium sulfate (CS) ternary systems for …

This research utilized machine learning (ML) techniques to forecast the thermal conductivity
(TC) of cement-based grouts for borehole heat exchangers. Nine commonly used ML …

Filling a borehole with proper grout is important for maintaining the safety and performance
of borehole heat exchangers (BHEs). The current grouts have problems of large shrinkage …

Thermal conductivity of mine backfill is vital for understanding the geothermal energy
extraction potential in deep underground mines. Geothermal energy extraction efficiency …

Thermal properties of grouting materials for borehole heat exchangers (BHE) are currently
analysed with varying measurement methods and analysis procedures, resulting in …

While heat pumps have been acknowledged as a key enabling technology to achieve Net
Zero goals, their uptake is limited by their performance and cost. In this paper, a simulation …

This paper describes the design, construction, validation, and calibration of a thermal
conductivity measuring apparatus for geothermal backfill materials in the range from 0.13 …

Since natural gas hydrates only exist stably at low temperature and high pressure, hydration
heat of cement slurry is easy to cause hydrate decomposition. Therefore, low-heat cement …
