▎ 摘　　要

NOVELTY - The geopolymer material has 175-280 pts. wt. silicon-aluminum mineral raw material, 100-130 pts. with alkali excitant, 80-100 pts. light aggregate, 28-50 pts. carbon material and 2-8 pts. methyl cellulose. The silicon-aluminum mineral raw material according to pts. wt. has granulated blast furnace slag powder 100-150 parts, fly ash 20-40 parts, silicon ash 30-50 parts, nano-silicon oxide 3-8 parts, nano 2-5 parts. aluminum oxide. The silicon-aluminum mineral raw material further has nano-reduced iron powder 10-15 parts and nano titanium dioxide 10- 15 parts. to pts. wt. USE - Geopolymer material with wave-absorbing and electromagnetic shielding functions in building material for underground engineering and strategic energy reserve projects, and electronic devices in strategic facilities. ADVANTAGE - The geopolymer material has good synergistic performance, fully using the lightweight aggregate to construct the conductive network in the geopolymer, making the light high-strength geopolymer material have the application field of broadening with wave-absorbing and electromagnetic shielding function. The lightweight aggregate is polyurethane light aggregate, clay, expanded polystyrene, perlite, at least one of hollow glass micro-bead, light aggregate density is 0.1-0.8 g/cm 3, and the carbon material according to pts. wt. has oxidation 8-15 parts graphene fiber 10-20 parts, 10- 20 parts, graphite 6-10 parts, carbon nano tube 4-6 parts, and methyl cellulose 2-8 parts. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of geopolymer material.
