Construction joints should be provided in slabs and beams at locations where it is necessary to stop pouring concrete temporarily and resume later. These joints are typically located at points of minimum shear and bending moment to ensure the structural integrity of the slab or beam. They should be planned keeping in mind the structural design and construction sequence to avoid any stress concentrations or discontinuities. Additionally, joints should be properly sealed and reinforced to ensure durability and prevent any further movement or cracking.
Construction joints in slabs are essential for accommodating movement and controlling cracking due to temperature changes, shrinkage, and settling. They help ensure that the concrete can expand and contract without causing damage to the structure. Additionally, these joints provide a clear stop for each pour, allowing for better workability and a more uniform finish. Properly placed construction joints also facilitate maintenance and repair in the future.
because large slabs of concrete have expansion joints between them.
Large concrete slabs should be laid with expansion joints to accommodate the natural expansion and contraction of the material due to temperature fluctuations. Without these joints, the slabs can experience cracking, warping, or buckling as they shift. Expansion joints allow for movement while maintaining structural integrity, ensuring the longevity and functionality of the concrete surface. This practice minimizes maintenance costs and enhances safety by preventing surface failure.
Gaps are left in concrete slabs to accommodate expansion and contraction due to temperature changes, which can prevent cracking. These gaps, often referred to as expansion joints, allow for movement without damaging the structure. Additionally, they can help manage water drainage and prevent moisture buildup, which can lead to further structural issues. Proper spacing and placement are crucial for maintaining the integrity of the concrete.
The best location to set the construction joint is less shear force impact. e.g:In slabs;it is better to locate between the supports.

Concrete slabs are a common building material. Sometimes they are re-enforced with steel roods for extra stability. Concrete slabs are either prefabricated or created insitu.

Those are expansion joints. During the changing seasons with varying temperatures, the slabs expand and contract. The spaces allow the slabs to expand without cracking the concrete.
Mivan Technology involves columnless , beamless construction but usually all walls & slabs are of 150mm concrete and slabs as a whole. Pre-planning is required to leave openings for doors,window & services shafts in shuttering itself.

Concrete expands and contracts depending on the temperature. The strips are called expansion joints.
