To soften concrete that has hardened in a truck, you can try applying a liberal amount of water to the surface and covering it with a wet burlap or plastic sheeting to retain moisture. This method can help rehydrate the concrete and make it easier to work with, but it may not completely reverse the hardening process. Alternatively, using a concrete softener or chemical agent designed for this purpose can also be effective. However, results can vary, and prevention is key, so it's essential to work quickly while the concrete is still fresh.
Regular sugar will cause the concrete to never set.

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.

Yes, you can paint concrete surfaces to give them a fresh look and enhance their appearance.
Density of M30 and any fresh concrete is 2400kg/cu.m and reinforced concrete density you can take 2500 kg/cu.m

The Kool Deck topping can be applied on BOTH fresh concrete and existing concrete with the PTA bonding agent. It is most commonly applied on fresh pours because of labor and timing simplicity, which lowers cost. Kool Deck toppings applied on existing concrete bond equally well as a Kool Deck surface applied to a fresh pour.

Formwork serves several important functions in construction, including providing support for fresh concrete, shaping the concrete to the desired form, ensuring the structural integrity of the concrete element, and helping to achieve a smooth finish on the concrete surface.
