Abstract:The species of raw material, gel material content, water-binder ratio, amount and ratio of mineral admixture, and selection of formwork system are changed to explore the change law of the concretes compressive strength, resistance to chloride ion permeability, and appearance quality. With a water-cement ratio ranging from 0.34 to 0.38, cementitious material greater than or equal to 420 kg/m3, mix with 30% to 60% of fly ash and slag in the ratio of 1颐2, mix with 20% of the super-fine limestone powder, as well as the use of defoamer and air-entraining agents, we may improve the polycarboxylate superplasticizer. Under the strict control of the quality of raw materials, and painting polyurethane template paint, we can make anticorrosive fair-faced concrete with a strength of greater than C40, 56 d chloride ion diffusion coefficient of less than 3.0×10-12 m2/s, and the appearance meeting the JGJ 169—2009“Technical regulations for application of fair-faced concrete”.
