It would require certain tools such as a jackhammer or possibly a sludge hammer. And the person working on it should wear safety goggles

Micro structure of concrete with nano materials gets changed like anything and is resulting tremendous increase in compressive strength apart from increase in specific surface area.
Prefabricated is a general term for anything that is assembled in a factory rather than on-site. Precast would be specifically applicable to anything that could be formed in a mold (concrete, perhaps glass, metal, etc.).
Concrete is made of a mixture of cement, aggregate (small stones), fine aggregate (sand), water and other chemical additives. When mixed the wet concrete will remain so for Most people assume that set concrete has no water in it, this is not so, as the water content helps bond the aggregates and cement, this process is known as Hydration. Concrete with no water in it would crumble to dust. Adding more water to the mix will make a concrete that is easier to work, while less water will produce a stronger, more durable concrete. After initial setting of the concrete, a slow amount of water loss is expected due to the concrete drying, it can take anything up to a year for water to stop evaporating slowly out of the concrete. So for this reason the answer to your question is yes, dry, set concrete will weigh less than wet concrete, but for anything up to a year it will keep getting lighter, due to waterloss.
no
anything freeze dried
smash it of with a sledge hammer
They didn't do anything about it, it dried.
no, it will weigh heavier because it will dry into cement when mixed with water and the weight of water will add to the weight of the concrete.
There does not appear to be anything that can be put in your pool to redeye your concrete in the pool dark blue. This can only be achieved by draining the pool and painting the concrete a dark blue color.
NO ! It is not advisable to eat anything that is molding !
Drain-O, not the best for the fish or anything for that matter, but cleans just about anything.
Let bleach soak on it than maybe power-wash it away.
Anything freeze dried.

concrete is basically strong in compression....anything which is having tensile strength reinforces concrete To reinforce concrete company's will use a fibre mesh which has loads of microscopic fibres and they bind the concrete together stronger. also in concrete slabs builders will usually tread re-in-forced steel grids into the mix
