A trowel is a flat, steel tool with a handle, meant to "butter" on drywall grout, or to smooth the surface of newly-placed concrete, much like you smooth out the icing on top of a cake. "To trowel" means to smooth a concrete or grout surface, using a trowel.
Green concrete could mean two different things. It could mean that the concrete isn't cured yet, or it could mean that it is supposed to be environmentally friendly.
Main function of the lean concrete is to provide the uniform surface to the foundation concrete and to prevent the direct contact of foundation concrete from the soil. Lean concrete is used under the foundations.
The binder in concrete is usually cement. Cement causes the aggregate and sand to bind together mechanically and harden to make a solid surface.
Curing compounds are used to slow or reduce evaporation of moisture from concrete. There are several curing compounds in use, but all form a membrane over the concrete's surface.

Pouring a concrete slab is the pouring of a fresh unset concrete mix into a prepared area, where it is finished by floating etc to give the required surface, and it sets to form a slab.
For securing screws into a concrete surface, use a masonry drill bit specifically designed for drilling into concrete. These drill bits have a carbide tip that can effectively penetrate the hard surface of concrete.
To smooth out concrete effectively, you can use a concrete float or trowel to level the surface while it is still wet. After that, you can use a concrete finishing broom to create a textured surface for better traction. Finally, you can apply a concrete sealer to protect the surface and give it a polished look.
To properly finish a concrete floor for a smooth and polished surface, follow these steps: Start by leveling the concrete surface with a bull float. Use a power trowel to smooth out any imperfections. Apply a concrete densifier to strengthen the surface. Polish the concrete with a series of progressively finer grit diamond polishing pads. Seal the surface with a concrete sealer to protect and enhance the finish.
To achieve a smooth and shiny finish when working with concrete, you can follow these steps: Start by properly preparing the concrete surface by cleaning it and removing any debris. Use a high-quality concrete mix with a fine aggregate to reduce the chances of surface imperfections. After pouring the concrete, level and smooth the surface with a trowel. Allow the concrete to partially set before using a steel trowel to further smooth the surface. Once the concrete is fully set, use a concrete sealer or polish to achieve a shiny finish.
The inside surface of forms are oiled to prevent the concrete from sticking to the formwork when it dries. This allows the formwork to be easily removed without damaging the concrete surface. Oil also helps in creating a smooth finish on the concrete.

Yes, you can lay pavers over concrete to create a new patio surface.
That's sort of a strange question. A concrete slab is a horizontal surface -- it's meant to be a surface you stand on or build things on. Concrete blocks are usually used for vertical surfaces -- walls. I believe that poured concrete walls are more expensive than concrete block walls. You wouldn't use concrete blocks as a substitute for a concrete slab.
The best method for repairing a concrete patch on a damaged surface is to clean the area thoroughly, apply a bonding agent, mix and apply a concrete patching compound, and finish with a trowel for a smooth surface.
