Abstract

The invention belongs to the technical field of building materials, and particularly relates to high-toughness concrete. Aiming at the shortcomings of the prior art, the invention provides high-toughness concrete capable of meeting the safety requirement in a high-rise building. The high-toughness concrete provided by the invention is characterized by comprising 20-25 parts of cement, 17-19 parts of fly ash, 22-29 parts of mineral powder, 8-12 parts of sand, 21-24 parts of gravel, 11-23 parts of metal powder, 2-6 parts of mica and 1-1.5 parts of additives. The high-strength concrete capable of meeting the safety requirement in a high-rise building and having the advantage of high toughness provided by the invention comprises 15-18 parts of master batch, 7-15 parts of fly ash, 19-27 parts of mineral powder, 22-30 parts of gravel and 15-17 parts of limestone. In conclusion, the high-toughness concrete provided by the invention has the advantages that the strength is high and the building safety is enhanced.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a high-toughness concrete. Background technique [0002] Due to the shortage of land area, the construction industry, especially the residential construction industry, is more and more inclined to the development of high-rise residential buildings. In this way, the requirements for the toughness and span of building materials are greater, but the existing concrete materials cannot fully meet this building demand. , so it still needs continuous improvement. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a high-toughness concrete that can satisfy safety requirements in high-rise buildings. [0004] The technical solution of the present invention is a kind of high-toughness concrete, and its components include cement, fly ash, mineral powder, sand, stone, metal powder, mica and admixture, and the proportion is...
