A kind of energy saving and environment friendly frost-resistant concrete and preparation method thereof
Technical field
The present invention relates to building concrete technical field, be specifically related to a kind of energy saving and environment friendly frost-resistant concrete and preparation method thereof.
Background technology
Concrete usually makes Binder Materials with cement, sand, masonry gather materials, coordinate by a certain percentage with water (can containing additive and admixture), agitated and the cement concrete that obtains, also referred to as normal concrete, it has that easy-formation, energy consumption be low, good endurance, low price and be combined the advantage that can be made into various support mechanism with steel, is contemporary most widely used construction material, the development of human society is played a very important role
As concrete must the consumption that gather materials of one of additive very big, natural aggregate exhaustive exploitation, so as to quality also cannot meet the demand that existing concrete produces, current concrete there is also intensity difference, frost resistance is low, dry shrinkage is big, easily the deficiency such as generation cracking.Therefore, develop various artificial aggregate and find suitable substitute material, thus develop a kind of high intensity, freexing tolerance is good, dry shrinkage is little, the new concrete of the function such as heat-resisting not easy to crack, antibacterial, the needs to meet high-quality construction project become the technical barrier that this area is badly in need of solving.
In recent years, along with growth in the living standard and social progress, various solid wastes that people's daily life and industrial processes produce and urban construction are removed and are remake the solid waste etc. brought and annoying the living environment of resident always, and the process of waste and old clothes that more particularly can not continue to wear is always up a difficult problem.Solid waste is added in concrete as raw material by the present invention, it is achieved that the cyclic utilization of waste, decreases the pollution to environment, meets strategy of sustainable development requirement.
Summary of the invention
It is an object of the invention to provide a kind of energy saving and environment friendly frost-resistant concrete and preparation method thereof, to overcome the deficiencies in the prior art.
