The invention relates to concrete, specifically to a C35 low-gelatinizer self-compacting corrosion resistant concrete and its preparation method. According to the scheme of the invention, raw materials of the C35 low-gelatinizer self-compacting corrosion resistant concrete comprise the following ingredients: 180-300 kg/m<3> of cement, 30-80 kg/m<3> of fly ash, 220-640 kg/m<3> of fine river sand, 300-600 kg/m<3> of machine-made sand, 600-1100 kg/m<3> of 5-25mm cobblestone, 5-20 kg/m<3> of a polycarboxylate superplasticizer, 0.01-0.05 kg/m<3> of a thickening agent, 4-8 kg/m<3> of an early strength agent and 0.5-7 kg/m<3> of a corrosion inhibitor. The C35 low-gelatinizer self-compacting corrosion resistant concrete provided by the invention has small amount of a cementing material, has good fluidity and early strength, and also has good corrosion resistance. The invention has an important effect of promoting application of the C35 self-compacting concrete.
