In basic terms, you can not.
you can strengthen a reinforced concrete beam by application of a steel plate/frp up to a point where the area in the stress block under compression is at a max. allowable limit as stated in the code you are using. At this stage, the concrete is close to a crushing instantaneous failure and the beam can not be strengthened further.
You must form on top of the existing slab and drill in anchors to join the new concrete to the old this is called a cap
concrete grade and strength are both revalent since if grade increase setting time will be less and curing to be done propely so that concrete strength will reach higher. If concrete grade is low curing to done longer days upto intial setting time to reach proper strength
No do to the concrete settling the concrete on top would split
If you are using a traditional concrete mix you can increase the slump by increasing the water you add.

theywork well as long as you can get the existing concrete clean enough
Radiant flooring is an option if one has an existing concrete floor. The radiant flooring system is installed underneath the concrete floor to heat the concrete.
Full basement is the grade of concrete that is laid for foundation.

The grade of the concrete means the concrete compression resistance after 28 days. It is done in Newtons per square millimetre. A concrete of Grade C30 means that the concrete will have a compresion resistance (withstanding a compression) of 30 N/mm2 per square millimetre in 28 days.
Want to replace an existing subsided external concrete step.

we use M30 grade concrete commercial slabs like shopping malls . college buildings
