Method.
Background technique
Green concrete refers on the basis of commerical ready-mixed concrete, additional volume displaced rate be the coarse aggregate of 5%-25% simultaneously
A kind of new concrete for stirring evenly rapidly and being formed.Green concrete has several advantages that (1) greatly reduces contraction
Cracking.Coarse aggregate surface can absorb moisture during mix.After adding coarse aggregate in commerical ready-mixed concrete, in aggregate and concrete
Gel rubber material contact area increase, reduce the whole ratio of mud, therefore reduce concrete shrinkage crack.Meanwhile out of concrete
Portion's microstructure angle analysis, coarse aggregate contacts with each other and forms interlocking structure in green concrete, gives full play to skeleton function,
Advantageously reduce whole shrinkage cracking.(2) there is good mechanical property.Aggregate in normal concrete and gel rubber material it
Between there are one layer of weak interfacial transition zones, be the region for most easily producing damage and initial crack, be destroying concrete structure
Cradle and weak area, it is larger to the Effect on Mechanical Properties of concrete.And to can be improved this interface excessive for green concrete
Intensity.This is because coarse aggregate can absorb coagulation pedosphere during secondary mix in green concrete work progress
The moisture of face transition region reduces the water-cement ratio of interfacial transition zone, increases interfaces transition-area compactness, and then improve concrete
The mechanical property of interfacial transition zone.According to pre-stage test, the cubic compressive strength of green concrete can be improved 20%~
30%.(3) volume stability is good.Coarse aggregate contacts with each other and forms interlocking structure in green concrete, gives full play to skeleton institute
With, be conducive to resist concrete coagulation during volume contraction.(4) cement consumption is significantly saved.Green concrete is being made
During work, since partial gel material (water, cement, sand, mineral powder etc.) is replaced by the lower coarse aggregate of cost, same
Cement 10%~25% can be saved under the operating condition of sample, significantly attenuating project cost, while be conducive to save the energy, reduce carbon row
It puts, is good for the environment.This is also the origin of green concrete name.
Although green concrete has many advantages, such as, there is very big difficulty in practical projects.Commerical ready-mixed concrete
