3. product characteristics of filling expansion joints in concrete  :

a: fast recovery of traffic: for high-speed, national, provincial, municipal, airports and
other transportation can be achieved 1 hours.
b: high compressive strength: 1h more than 25Mpa, 2h more than 35Mpa, 1d more
than 60Mpa, 28d more than 80Mpa.
c: high flexural strength: 1h greater than 5Mpa, 2h greater than 7.5Mpa, 1d more than
10Mpa, 28d more than 11Mpa.
d: good adhesion properties: bond pull strength reaches 2.8Mpa, to solve the
traditional material bond is not strong or problems can easily lead hollowing cracks.
e: the product toughness and impact resistance: 5-10 times that of ordinary concrete.
f: the thermal expansion coefficient: basically consistent with the primary concrete.
g no shrinkage cracks: between the original concrete and no shrinkage cracks after
solidification.
h: frost and salt corrosion: cold-resistant, corrosion-resistant sulfate, non-toxic,
non-corrosive.
