RESEARCH INTO THERMAL CONDUCTIVITY OF GROUT MIXTURES USED FOR HEAT PUMP BOREHOLES
Original language description
The article summarises some basic knowledge obtained by research into the properties of mixtures used in the grouting of boreholes used for heat pump installation. Already for a long time, our Institute has been concerned with research into the thermal permeability of various types of grout mixtures ? from the commonly used cement-clay mixtures, which have good grouting properties but rather bad thermal transmittance, to the mixtures (available on the market) that are pre-prepared and are to be only mixed with water at a given ratio. On the one hand, they have better thermal properties, but on the other hand, they are more expensive and if some of them are injected into boreholes they will harden in several days so that the function of protection in relation to the heat exchanger will disappear. Our Institute co-operates with the Institute of Geonics of AS CR and AGH Kraków in making comparative measurements of thermal conductivity and thermal permeability of these various types of gro
