GROUNDING RESISTANCE-REDUCED COMPOSITION AND HARDENED PRODUCTS THEREBY

摘要

PURPOSE: A grounding resistance-reduced composition containing water adsorbing mineral and water absorbing polymer is provided which has excellent grounding effect and no annual variation of grounding resistance, and forms grounding electrodes with high electric conductivity. CONSTITUTION: The composition comprises 18-57wt.% of at least one water adsorbing mineral selected from zeolite, bentonite and kaolin and 0.1-5wt.% of water absorbing polymer, 0.1-5wt.% of at least two PAN-based carbon fiber selected from carbon fibers having 1, 3, 6, 9 and 12mm of length, as an electric conductivity material, 38-77wt.% of binder, 0.1-2wt.% of high plasticizer, 0.1-4wt.% of setting agent. The hardened product comprises 100pts.wt. of resultant composition and 30-50pts.wt. of water.
