Expansion Joints
An expansion joint or movement joint is an assembly designed to safely absorb the heat-induced
expansion and contraction of various construction materials, to absorb vibration, to hold certain parts together, or to allow movement due to ground settlement or earthquakes. They are commonly found between sections of buildings, bridges, sidewalks, railway tracks, piping systems, ships, and other structures.Because expansion joints are installed at a late stage in construction, some of these movements will have at least partly already taken place. Consequently, expansion joints have to facilitate a smaller degree of overall movement than a bearing at the same location.
Advantage:
1. High strength:1 h comprehensive strength≥28Mpa,1 d comprehensive strength is ≥60Mpa,28 d comprehensive strength is≥80Mpa.It can fully meet the needs of the rapid repair and strength requirements.
2. Bond performance is good, frost resistance, corrosion resistance, non-toxic, odorless.
3. Crack resistance performance is good.
4.Product strength toughness and impact resistance performance is the 3-5 times of the
common cement .
5.Small color difference and seamless with the original concrete pavement .
Bridge expansion can be divided into three types as below shows:
Comb-type expansion joints
Plate-rubber expansion joints
TST expansion joints
