（1）excellent plasticity retention ability
it can solve the problem of fast slump loss of concrete and failure to pump.
（2）reduce the amount of concrete cement
good slump protection, no need to add water twice, keep the water-cement ratio unchanged, single concrete can reduce the amount of cement 20-30kg, reduce the cost of 8-10 CNY /m3.
it can make the concrete prepared with 5-10% river sand with good workability and pumping performance.
（4）large-scale waste reduction cost
100% of the river sand can be replaced by stone ore tailings (stone debris), effectively solving the problem of river sand resource shortage, and at the same time, the material cost can be reduced by 10-20 CNY /m3.
（5）strong technical support
2 doctors and 3 professor-level senior engineers can provide professional technical consulting services on concrete and related issues for partners.
