▎ 摘 要
NOVELTY - A active powder concrete comprises cement, graphene, silica fume, fly ash, sand, water reducing agent, and water. USE - Active powder concrete. ADVANTAGE - The graphene reinforced active powder concrete has enhanced dynamic compressive strength, peak strain, ultimate strain and impact toughness due to the addition of graphene. At a strain rate of 200-800/second, the dynamic compressive strength of concrete can be increased by 63.9% with a blend of 0.25-0.5% graphene, dynamic peak strain and dynamic ultimate strain can be increased by 66% and 32.7%, and impact toughness can be increased by 117%.
