NOVELTY - Cement gel material comprises cement base material, graphene material and polycarboxylic acid water reducing agent, and the graphene material is used in an amount of 0.02-0.04% of the mass of the cement base material. The cement base includes aggregate, portland cement and belite cement. USE - Used as cement gel material. ADVANTAGE - The material has improved flexural strength by introducing graphene material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) producing cement gel material, comprising providing a dispersion in which the graphene material is dispersed, further containing the polycarboxylic acid water reducing agent in the dispersion, where the polycarboxylic acid water reducing agent is provided in a form dissolved in water and the cement base is mixed with the dispersion; and (2) cement preform, comprising cement gel material.
