Joints in concrete 456/IRC 58
Concrete joints are provided to compensate thermal expansion and contraction.
The structural separation of concrete members to allow independent movement without damage. They are designed to absorb thermal expansion of concrete. They are commonly provided in bridges, slabs, railways.
Bitumen Fibre Board, Dura Board Normally structures exceeding 45 m in length are designed with one or more expansion joints.
The pre planned cutting grooves are given in concrete where occurrence of cracks are expected. The depth of groove is 25% of total thickness of the concrete member. Grooves are given in a straight line. These are due to shrinkage or temperature variations.
Cutting grooves with blade. Providing glass strips panels not exceeding 3 sqm area in flooring
When the work cannot be completed in a single day, construction joints are provided in concrete. These are common in big rafts, beams where joint is provided at L/3
