摘要

The self-compacting concrete comprises a portion of 340 kg blast furnace cement per m 3>concrete, where the blast furnace cement contains a portion of Portland cement clinker (20-34 mass%) and a portion of blast furnace slag (66-80 mass%), a portion of 300 kg Portland composite cement per m 3>concrete, where the Portland composite cement contains a portion of Portland cement clinker (65-94 mass%) and a portion of additives (6-35 mass%), a portion of 300 kg limestone flour per m 3>concrete, and a portion of 1400 kg coarse aggregate made of sand, gravel or crushed stone per m 3>concrete. The self-compacting concrete comprises a portion of 340 kg blast furnace cement per m 3>concrete, where the blast furnace cement contains a portion of Portland cement clinker (20-34 mass%) and a portion of blast furnace slag (66-80 mass%), a portion of 300 kg Portland composite cement per m 3>concrete, where the Portland composite cement contains a portion of Portland cement clinker (65-94 mass%) and a portion of additives (6-35 mass%), a portion of 300 kg limestone flour per m 3>concrete, a portion of 1400 kg coarse aggregate made of sand, gravel or crushed stone per m 3>concrete, where the coarse aggregate has an aggregate size of maximum 8 mm, a styrene-acrylate copolymer with a portion of 5-15 mass% to the mass of the blast furnace cement and/or Portland composite cement, a high performance flow agent based on polycarboxylate ether with a portion of maximum 2 mass% to the mass of the blast furnace cement and with a water/cement ratio of maximum 0.5 and/or Portland composite cement and with a water/cement ratio of maximum 0.55, and color pigments. An independent claim is included for a method for producing a self-compacting concrete.
