High thermal conductive cementing material capable of enhancing heat exchange performance of heat exchange system of floor heating

The invention discloses a high thermal conductive cementing material capable of enhancing the heat exchange performance of the heat exchange system of floor heating. The cementing material is composed of the following components by weight: 100 grams of cement, 50 to 200 grams of steel slag or copper mine slag, 150 to 300 grams of quartz sand, 0.8 to 3.0 grams of antifoaming agent, and 1.2 to 3.6 grams of water reducer. On the construction site, water accounting for 40 to 50% of the total weight of cement and steel slag/copper mine slag is added, and then the mixture is evenly stirred and poured into drill holes. The provided cementing material has the advantages of high thermal conductivity and good workability, can expand slightly, and thus can fully fill the drill holes. So that the heat exchange pipes can be tightly combined with the rock stratum, and the heat exchange performance is enhanced. The high thermal conductive cementing material can effectively protect heat exchange pipes from underground water corrosion, thus the service life of heat exchange pipes is prolonged, and the system operation risk is reduced. Furthermore, the cementing material has the advantages of low price, long service life, easily-available raw materials, and no pollution to environment.
