▎ 摘 要
NOVELTY - Cement-based electromagnetic developing composite material comprises 100 pts. wt. cement, 0.4-0.6 pts. wt. nano-graphene, 0.4-0.6 pts. wt. nano-Iron(II,III) oxide powder, and 0.1-0.5 pts. wt. graphene dispersant. USE - The composite material is useful in geological detection (claimed). ADVANTAGE - The composite material: has the characteristics of high dielectric constant, can develop geological media with similar dielectric constants underground, enhance the reflection effect of the interface, and increase the detection depth and precision of the ground penetrating radar. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of the cement-based electromagnetic developing composite material comprising using 100 pts. wt. cement, 0.4-0.6 pts. wt. nano-graphene, 0.4-0.6 pts. wt. nano-Iron(II,III) oxide powder, and 0.1-0.5 pts. wt. graphene dispersant, and adding nano-graphene, nano-Iron(II,III) oxide powder and graphene dispersant to the cement , uniformly mixing to obtain the cement-based electromagnetic developing composite material.
