Abstract: The horizontal ground heat exchanger has been extensively employed to collect geothermal energy from mine backfill bodies. A novel method for avoiding thermal interference using the thermal influencing radius coupling pipe ...

Abstract: In this study, the mechanical behavior of novel fully grouted cable rock bolts made of basalt fiber–reinforced polymer (BFRP) was investigated, which included pullout and double-shear joint behavior. Three BFRP cables were ...

Abstract: Phase change materials (PCMs) can absorb or release latent heat by changing their physical state within a certain temperature range, but directly added to the road, the mix can easily leak. Cement stone is an excellent ...
