Abstract: The Seebeck coefficient of plain cement paste is usually less than 1  μV/°C. To enhance the thermoelectric performance of cement composites, a kind of MnO2 powder was synthesized and used as a thermoelectric component in ...

Abstract: Abstract During shield tunnel construction, tunnel stability and surface settlement deformation are often improved by backfill grouting; thus, studying the failure mechanisms of grout-reinforced tunnels is significant for ...
