NOVELTY - A crack-resistant low-carbon high-performance concrete comprises 390-410 kg/m3LC3 cementitious material, 640-660 kg/m3sand, 1000-1100 kg/m3stone, 150-170 kg/m3water, 8.0-8.5 kg/m3water reducing agent, 0.1-0.3 kg/m3activated carbon fiber and 0.1-0.3 kg/m3graphene oxide. The LC3 cementitious material is made of cement, calcined clay, limestone powder and gypsum. The water is made of wastewater from a stirring station and clean water. USE - Crack-resistant low-carbon high-performance concrete for use in building engineering application. ADVANTAGE - The low-carbon high-performance concrete is economical and environmentally-friendly, has excellent crack resistance, mechanical property and durability, effectively reduces carbon emission, and promotes the resource utilization of the stirring station wastewater and LC3 cementitious material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of crack-resistant low-carbon high-performance concrete, which involves mixing and grinding the weighed calcined clay, limestone and gypsum, mixing and stirring with cement to obtain LC3 cementitious material, mixing and stirring activated carbon fiber and graphene oxide dispersion, filtering, washing, and drying to obtain an activated carbon fiber/graphene oxide composite material, and mixing and stirring the obtained LC3 cementitious material, activated carbon fiber/graphene oxide composite material, sand, stone, water and water reducing agent.
