JGN808 Segmental bridge adhesive

1.High strength, elastic modulus, low creep, waterproof, corrosion resistance.
2.High thixotropic paste, easy to stir and apply, no sagging, no dripping.
3.Easy to compact, no water seepage, strong bonding ability with concrete, load transfer.
4.Construction in different climates, wet surfaces, low temperatures, stronger adhesion in dry conditions.
5. Long operation time, rapid solidification, rapid strength development, minimal impact on prestressed tensioning.
6.Observable color difference, mixing uniformity, consistency with concrete after mixing.
7.Good wettability with concrete, no strict bonding surface treatment needed.
8.Self-lubricating effect before curing, tight adhesion, no water seepage, corrosion protection for reinforcements.
9.Good toughness, fatigue resistance, impact resistance.
10.Safe and non-toxic.
