In, the regeneration brick aggregate pervious concrete can be obtained after being uniformly mixed, the regeneration brick aggregate mixed is permeable mixed
Solidifying soil aggregate surface slurry package is uniform and glossy.
Wherein:
The when a length of 30~60s being stirred described in step 1)；
Additional water and uniform mixing must be added according to saturated water absorption in regeneration brick aggregate described in step 1), prewet 20 in advance
~30h；
The when a length of 60~90s being stirred described in step 2)；
The when a length of 120~150s being stirred described in step 3).
The utility model has the advantages that compared with prior art, the present invention has the advantage that
1, construction waste masonry is prepared regeneration brick aggregate pervious concrete as regeneration brick aggregate to be a kind of by the present invention,
Prepared using it regeneration brick aggregate pervious concrete self weight it is low, water absorption rate is high, good water-retaining property, it is good to water body purification effect,
It is low in cost, it can be widely applied to riverbank, the places such as slope protection, roadbase are mated formation；
2, present invention selection promotes the cohesiveness of cement slurry using silicon ash and hydroxypropyl methyl cellulose, enables slurry
It is enough to be preferably wrapped in brick aggregate surface, and do not easily lead to that slurry fluidity is excessive and plug-hole；Silicon ash is to regeneration brick aggregate simultaneously
The promotion of pervious concrete intensity is made that contribution；
3, present invention selection replaces part of cement to reduce cement consumption using a large amount of lithium ground-slags to improve cement slurry water conservation
Property and cohesiveness, improve pervious concrete water storage satisfy outlet capacity；The micro-packing effect of lithium ground-slag can optimize cement slurry, mention
