▎ 摘　　要

NOVELTY - Modified anti-chlorine ion permeable marine engineering concrete comprises 450-650 pts. wt. Portland cement, 280-360 pts. wt. water, 1400-1600 pts. wt. aggregate, 20-30 pts. wt. mineral admixtures, 4-8 pts. wt. water reducing agent and 100-120 pts. wt. graphene oxide-silver nano fluid. The aggregate gradation is 15-25 pts. wt. 0.075-0.15 mm aggregate, 65-85 pts. wt. 1.18-2.36 mm aggregate and 150-170 pts. wt. 9.5-16mm aggregate. The mineral admixture comprises 50 pts. wt. fly ash and 50 pts. wt. slag. The water reducing agent is polycarboxylic acid water reducing agent. USE - The modified anti-chlorine ion permeable marine engineering concrete is useful in ocean engineering and concrete building. ADVANTAGE - The concrete: has high durability, surface roughness of graphene oxide and mechanical property; reduces the agglomeration of composite nano particles; and prevents the corrosion of reinforcing steel bar. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the modified anti-chlorine ion permeable marine engineering concrete.
