The concrete's surface will invariably crack under strain and may weaken when it grows and compresses. And I think this is because of the environment. Concrete joints are the sole way to prevent this. So let me walk you through the construction joint in concrete.

What is a construction joints in cement concrete?
In order to account for the material's seasonal growth and contraction, concrete is put in joints throughout the structure. Concrete fitters will anticipate which areas and how the concrete may crack in order to prevent cracks. According to their evaluation, they will make, cut, drill, and position joint placers in various places. These pre-formed fractures will guarantee that the concrete surface has room to grow and compress. It is without damaging the nearby structures and will assist the surface to perform much better generally.
These connections may occasionally need to be installed by contractors in order to stabilise the wall or flooring. The surface would be extremely unstable and vulnerable to harm without these joints. These connections will provide the concrete room to flow and eventually merge. The adjacent structures won't be affected by the concrete slab's growth and contraction. Because they are separate from them. So now you know what is a construction joint in a concrete.
How to do the sealing and positioning of joints?
1) Positioning the Joints
In order for the joints to be functional, they must be spaced uniformly apart and must reach at least one-fourth of the surface. As soon as the concrete is finished, within 8 to 12 hours, unmanaged cracks can readily appear. So ensure to cut the seams as soon as you can.
2) Sealing the joints
Joint sealants shield them from humidity, dust, and unwanted material. You don't need to be concerned about sealers putting pressure on the joint. Because they are flexible enough to support the growth and contraction of the concrete. Additionally, sealants will make the concrete look more pleasing to the eye and, in some cases, hide joints.
I hope you understood the concept of the construction joint in concrete.
