Method.
Background technology
Green concrete refers on the basis of commerical ready-mixed concrete, additional volume displaced rate for 5%-25% coarse aggregate simultaneously
A kind of new concrete formed by stirring rapidly.Green concrete has following advantage：(1) contraction is greatly reduced
Cracking.Coarse aggregate surface can absorb moisture during mix.Added in commerical ready-mixed concrete after coarse aggregate, in aggregate and concrete
The increase of gel rubber material contact area, the overall ratio of mud of reduction, therefore reduce concrete shrinkage crack.Meanwhile, out of concrete
Coarse aggregate contacts with each other and forms interlocking structure in portion's microstructure angle analysis, green concrete, gives full play to skeleton function,
Advantageously reduce overall shrinkage cracking.(2) there is good mechanical property.Aggregate in normal concrete and gel rubber material it
Between there is one layer of weak interfacial transition zone, be the region for being easiest to produce damage and initial crack, be destroying concrete structure
Cradle and weak area, it is larger to the Effect on Mechanical Properties of concrete.And can to improve this interface excessive for green concrete
Intensity.Because in green concrete work progress, coarse aggregate can absorb coagulation pedosphere during secondary mix
The moisture of face transition region, reduces the water-cement ratio of interfacial transition zone, increases the compactness in interfaces transition-area, and then improve concrete
