Concrete additive and high-strength concrete prepared from same
The invention relates to the technical field of concrete additives, and discloses a concrete additive and high-strength concrete prepared from the same. The concrete additive comprises the following components in parts by weight: 15-30 parts of a modified polycarboxylate superplasticizer, 5-10 parts of sodium dodecyl sulfate, 1-10 parts of a composite corrosion inhibitor and 50-60 parts of water. The high-strength concrete is prepared from the following components in parts by weight: 20 to 30 parts of cement, 100 to 120 parts of coarse aggregate, 60 to 65 parts of fine aggregate, 10 to 15 parts of fly ash, 15 to 25 parts of water and 1 to 10 parts of concrete additive.
