: .>Anti-segregation performance: High-strength non-shrinkage grouting material overcomes the problem of too much water added during on-site use segregation phenomenon caused.
: .>
: .>
: .>☆
: .>
: .>Green and environmentally friendly: does not contain benzene series, halogenated hydrocarbons, formaldehyde , heavy metals and other components, it is non-toxic, odorless, non-polluting, non-flammable and non-explosive, and can be transported as general cargo.

: .>Strong durability: After millions of fatigue tests
: .>
: .>There is no significant change in the intensity of the freeze-thaw cycle experiment. After soaking
: .>
