▎ 摘　　要

NOVELTY - Preparation of sensing material involves preparing aqueous solution of graphene and nano conductive carbon black, adding cement as a binding material, adding water and sand, setting water-cement ratio to 0.28-0.7 and glue-sand ratio to 1:8-1:3, stirring the cement and the sand using a stirrer for 2-5 minutes, pouring the prepared solutions of graphene and the nano conductive carbon black, continuously stirring and then pouring mixture into a mold. USE - Preparation of sensing material for monitoring of concrete sulfate erosion. ADVANTAGE - The sensing material having excellent sensitivity, elasticity modulus and desired thermal expansion coefficient is economically produced by simple method. The sensing material is not damaged due to stress deformation difference and temperature deformation difference. The sensing material is stable in performance and durability.
