Fig. 2From: Doped bentonitic grouts for implementing performances of low-enthalpy geothermal systemsDiagram of the repeated measurements of thermal conductivity obtained on the starting and doped (+ 5 and + 10% of graphite powder) bentonitic grouts. Symbols are as follows: diamonds for the starting grout; squares for the grout + 5% of graphite powder; triangles for the grout + 10% of graphite powderBack to article page
