Beschreibung
Zusammenfassung:	The invention relates to a high-thermal-conductivity and high-ductility geopolymer composite material and an energy pile, the composite material comprises the following raw material components in parts by weight: 20-30 parts of fine aggregate, 70 parts of a cementing material, 0-10 parts of copper powder, 0-2% of PVA (Polyvinyl Alcohol) fiber and the balance of alkali-activated liquid, and the volume mixing amount of the PVA fiber is 0-2%. The ratio of the total mass of the fine aggregate, the cementing material and the copper powder to the addition amount of the alkali-activated liquid is 1kg: 250-360mL. Compared with the prior art, the polymer composite material disclosed by the invention is simple in preparation process, has high ductility and environmental protection property, and keeps high strength at the same time. In addition, the heat conductivity coefficient can be increased, so that the heat transfer efficiency of the energy pile is improved. The double-W-shaped exchange liquid pipeline is firmly f
