Rapid bridge expansion joint repair product have below advantages:
1.1h open to traffic:Fast with strength,2h compressive strength ≥33Mpa,
2h flexural strength ≥5Mpa,Fully meet bridge rapid repairing,reduce traffic congestion.
2.Bonding tightly:no break and fall off from normal concrete under heavy load.
3.High strength:Compressive & flexural strength in late period, both reach 2-3 times of normal concrete.
Compressive strength:1d≥60Mpa, 28d≥80Mpa,Flexural strength ≥10Mpa.
4.Good toughness:Impact resistance strength is 8-10 times of normal concrete impact resistance strength
5.No drying cracks in repaired area and original concrete
6.Good match:Heat expansion and cold contraction coefficient is nearly same with original concrete.
7.Small color difference: Color of repaired area is close to original concrete.
