The invention relates to fair-faced concrete. The fair-faced concrete is prepared from a binding material, a composite
water reducer, water and aggregate, wherein the amount of the binding material in the fair-faced concrete is 380-480kg / m<3>; the binding material comprises the following components in parts by weight: 45-70 parts of
cement, 10-30 parts of
coal ashes and 20-50 parts of granulated blast-furnace
slag; the amount of the composite
water reducer accounts for 0.5%-1.1% of the binding material; the composite
water reducer comprises a polycarboxylate
superplasticizer, a
defoamer, an air entraining agent and a
tackifier; the amount of water accounts for 0.32-0.45 times of the binding material; and the balance is the aggregate. The invention further relates to an application of the fair-faced concrete in ocean
engineering construction. The fair-faced concrete provided by the invention is excellent in
chloride ion permeability resistance, smooth in surface, and uniform in color and luster; the sum of the area of air bubbles of which the surface area is greater than 1m<2> is not greater than 6*10<-4>m<2>; the
maximal diameter of the air bubbles is not greater than 5mm; the depth is not greater than 5mm; and the fair-faced concrete is low in
air content and bleeding rate, and can be used in an
ocean environment for a long period of time.
