Abstract: 
In present paper, typical high performance concrete with low water/cement ratio and mineral admixture was cured by evaporation reducer (ER) at plastic stage. Effect of ER on concrete duration was characterized by carbonation, electric flux and freeze thawing experiment. In order to illustrate the reason of duration improvement, neat cement with water/cement=0.4 was prepared and the microstructure with and without ER curing was discussed. Results pointed out that concrete with early curing at its plastic stage by ER could improve concrete durability through increasing cement hydration degree, optimizing pore structure and decreasing porosity.
