Abstract
The present invention relates to its preparation process of kind of green high performance concrete, concretely comprises the following steps and first adds 8 parts of 10 parts of cement, 10 parts of flyash, 20 parts of water, 8 parts of metakaolin, rubble stirring 80s；Then 5 parts of 3 parts of glass bead, coarse sand stirring 30s are added；Add 6 parts of 8 parts of nano silicon dioxide, 6 parts of graphene powder, ferromagnetic powder stirring 20s；It is eventually adding 8 parts of 8 parts of high-strength copper based alloy matrix powder, nano boron carbide silicon carbide whisker powder stirring 120s, concrete formation.The mixing of nano silicon dioxide, ferromagnetic powder, glass bead, graphene powder adds stirring, improves mobility and cohesiveness；The addition of high-strength copper based alloy matrix powder and nano boron carbide silicon carbide whisker powder improves the density and rigid of concrete, effectively realizes the high performance characteristics such as low electric flux, the durability of concrete.
Description
Technical field
The present invention relates to technical field of buildings, particularly a kind of its preparation process of green high performance concrete.
Background technology
The various physics of concrete nature residing during service, chemistry and biological factor etc. can all cause its structure
Destroy, in some instances it may even be possible to produce catastrophic consequence.Countries in the world account for total investment for construction in building maintenance with the investment reinforced
Proportion is all quite big, and the U.S. reaches 50%, and Britain reaches 70%.Inside concrete hole be influence durability key factor it
One, therefore the key for improving concrete durability is exactly to reduce the internal void of concrete, improves its own compactness.But
The high performance concrete is manufactured but to be negatively affected to environment, such as manufacture cement when burn calcium carbonate discharge carbon dioxide and
Sulfurous gas, forms acid rain, produces greenhouse effects, influences environment.Therefore it is to close very much to study a kind of green high performance concrete
Key.
