NOVELTY - A modified lithium-based concrete sealing and curing agent comprises 30-50 wt.% aqueous lithium silicate, 0-10 wt.% sodium silicate (excluding 0), 0-30 wt.% silica sol (excluding 0), 0.5-2 wt.% surfactant, 0.5-1 wt.% dispersant, 0.5-2 wt.% defoaming agent, 3-15 wt.% fluorosilicate, 0.02-0.3 wt.% graphene oxide and rest is water. USE - Modified lithium-based concrete sealing and curing agent. ADVANTAGE - The sealing and curing agent have excellent comprehensive performance, and improves structure strength, wear resistance and water resistance of concrete. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of modified lithium-based concrete sealing curing agent, which involves (S1) accurately weighing each raw materials, (S2) mixing aqueous lithium silicate, sodium silicate, fluorine silicate and graphene oxide, heating and stirring, cooling to room temperature, obtaining mixed solution (A), (S3) adding surfactant, continuously stirring until solution is clear, (S4) adding dispersant and defoaming agent and water continuously stirring, leaving undisturbed (X1) to obtain mixed solution (B), continuously adding silica sol, stirring and leaving undisturbed (X2).
