grades, design etc. Different ratio of expansion &
contraction between two different structures has to be

Expansion Joint is especially provided to maintain the
changes in the dimension of the concrete mass due to the
effect of temperature on construction material like steel,

conjuction with.Also entire part is not affected by any
settlement of base or related strucures.
