Water/Cement Ratio should not exceed 200 litres/m3 .
Packing factor: In a simple way it is the ratio between the mass of tightly packed (compacted) to the mass of lossely packed.
Self Compacting Concrete also known as SCC, is a concrete which compacts itself when placed without the help of manual compaction.
To pour self-leveling concrete properly, follow these steps: Prepare the surface by cleaning and priming it. Mix the self-leveling concrete according to the manufacturer's instructions. Pour the concrete onto the surface in a thin, even layer. Use a trowel or squeegee to spread the concrete and ensure it is level. Allow the concrete to self-level and cure according to the manufacturer's guidelines.

Self-leveling crack filler is beneficial for repairing cracks in concrete surfaces because it provides a smooth and even finish, reduces the risk of tripping hazards, prevents water infiltration, and helps to maintain the structural integrity of the concrete.
To use self-leveling concrete for a smooth and even surface, first prepare the area by cleaning and priming it. Mix the self-leveling concrete according to the manufacturer's instructions and pour it onto the floor. Use a trowel or squeegee to spread the concrete evenly across the surface. Allow the concrete to self-level and cure according to the recommended drying time.
Concrete it self may not but most concrete structures .Has rebar in them and that can .
Self-leveling concrete typically takes about 4 to 6 hours to dry completely.
One of the disadvantages of self-compacting concrete is that it can be quite costly. When it is mixed with other forms of concrete it can break down over time.
No, it's okay to leave on.
That depends on the concrete, as well as weather conditions, and the load the concrete would be subjected to. Concrete gains strength over time and the usual benchmarks are 7 days, and 28 days. At 28 days concrete has usually cured to nearly its maximum strength. For a concrete footing in a residential environment say a deck or home the concrete will usually cure for a minimum of three days before the formwork is removed and the rest of the structure is built. For a commercial or civil project the curing is subject to the engineers discretion.
To apply self-leveling concrete for a smooth and even surface, first prepare the area by cleaning and priming it. Mix the self-leveling concrete according to the manufacturer's instructions and pour it onto the floor. Use a gauge rake to spread the concrete evenly and a smoothing tool to remove any air bubbles. Allow the concrete to dry and cure according to the manufacturer's recommendations for a smooth and level finish.
