Grouting is one of the most commonly adopted technique for soil improvement and strengthening. Adding super plasticizers, accelerators, antifreezes, air entraining agent improves performance cement grout. The grout while injecting in sand column mainly depends on its fluidity property. Keeping it mind about water ratio, strength studied two sets experiments by with only another set added plasti...

Ground heat exchangers are surrounded by grout material, making it one of the most important components in geothermal energy applications since significantly affects system's thermal performance. The current study reviews different types materials and compares their thermophysical properties. critical parameter is grout's conductivity which always presents a proportional relation with efficienc...
