CEMENT PASTE WITH ELECTRICAL PERFORMANCE, METHOD FOR MANUFACTURING THE CEMENT PASTE, AND METHOD FOR MANUFACTURING CEMENT STRUCTURE USING THE CEMENT PASTE

摘要

PURPOSE: A manufacturing method of cement paste having electrical properties and a cement structure manufacturing method by using the cement paste manufactured by the same are provided to give piezoresistivity to the cement paste by mixing the carbon nanotubes having electrical properties into the cement paste. CONSTITUTION: A cement paste uses carbon nanotubes, silica fume, and cement as main components. The carbon nanotube content is 0.1-0.45 wt% based on the weight of the cement. The silica fume content is 10-30 wt% based on the weight of the cement. The carbon nanotube is a multi-wall carbon nanotube. A manufacturing method of the cement paste comprises the following steps: (S1) mixing the carbon nanotubes with silica fume and first dry mixing the same for a predetermined time; (S2) adding cement to the first dry mixed carbon nanotube-silica fume mixture and second dry mixing the same for a predetermined time; and (S3) adding water to the second dry mixed carbon nanotube-silica fume-cement mixture and mixing for a predetermined time.
