what are construction joints and movement joints
how construction joints is done?
construction joints are leave in RCC Slab one third of span.
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 are very useful, the expansion & contraction made is made in summer & winter season respectiely. In summer coz of temprature concrete get expansion in mm but it damage the structure, that's why construction joint is provided. Sunil Nagargoje TESPL

Expansion joints. Butt,lap,half-housed,mortise/tenon and mitre joints to name some common ones.
It is provided to avoid the verticle joints.
