Abstract
A method of manufacturing a composite granular grouting material according to the present invention comprises: mixing bentonite and auxiliary component; forming spherical composite granules by agglomerating the mixture of bentonite and auxiliary component; drying the formed composite granules; and forming bentonite layer having lower density for forming slurry outside the composite granules by mixing bentonite with the spherical composite granules and agglomerating the same. The grouting material according to the present invention has excellent thermal conductivity and water blocking capability.
