Beneficial effect：
Compared with prior art, the present invention has following advantages：
1st, the present invention can be used for clay brick as coarse-fine aggregate to prepare regeneration brick aggregate concrete to be a kind of, utilize its system
Thermal and insulating performance for the regeneration brick aggregate concrete gone out is more excellent, and the density of itself substantially reduces, its strength grade
Reach C30 and more than, density rating can be up to 1800；
2nd, present invention selection partly substitutes cement to lift the cohesiveness of brick aggregate concrete using silicon ash, makes slurry more
Be wrapped in brick aggregate surface well, avoid due to the density contrast between brick aggregate and slurry is larger and caused by segregation phenomenon；
3rd, water-cement ratio is reduced while the present invention is selected using high-performance water reducing agent to ensure mobility so that brick aggregate
Concrete can reach higher intensity；The use of silicon ash is also made that tribute for the strength enhancing of regeneration brick aggregate concrete simultaneously
Offer.
