▎ 摘  要

NOVELTY - A high-early strength low-heat silicate cement comprises 80-95 pts. wt. low-heat silicate cement clinker, 0-15 pts. wt. slag, 0-15 pts. wt. silica ash, 0.03-0.05 pt. wt. graphene oxide and 5 pts. wt. gypsum. USE - The high-early strength low-heat silicate cement is used for railway engineering. ADVANTAGE - The cement blocks invasion of corrosive medium, keeps low hydration heat of low-heat cement, has good crack resistance, and anti-chlorine ion and sulfate corrosion resistance, and is more practical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the high-early strength low-heat silicate cement comprising taking low-heat silicate cement clinker as base material, and slag, silica and graphene oxide as modifier, mixing with gypsum to obtain mixture and grinding until specific surface area is 300-350 m2/kg.
