Concrete is the basis of much of Civilization’s Infrastructure and much of its physical development. It is almost twice as much concrete is used throughout the world than all other building materials combined use.
Difference between PCC and RCC:
PLAIN CEMENT CONCRETE (PCC): – It is also called Cement Concrete (CC) or Binding Concrete.
This is a construction material which consists of Cement, Sand, Aggregate (Coarse and Fine) , Water and Admixtures.
· It is used for providing a rigid, level space and impervious bed to RCC in foundation.
· It is also used under flooring (stone, tile, wooden flooring etc., ).
· It is good at resisting compression.
· It can be used over Brick flat soiling or without Brick flat soiling.
· It is also used as filler like lump concrete which is mixer of Boulder and PCC.
Thickness: PCC is normally between 50 to 75 mm
Concrete Ratio: Normally used proportions are 1:2:4, 1:3:6, 1:4:8
Unit: Cubic Meter (Cum)
REINFORCED CEMENT CONCRETE (RCC) :-
Concrete is material with a mix of Cement, Sand, Aggregate and Water, that is good for Compression not in Tension….
To resolve this critical issue by reinforcing steel, by casting wet concrete around strong steel bars. When the concrete set and hardens around the bars, we get a new composite material, REINFORCED CONCRETE (RCC). So it is a good material which works good either in Compression or Tension.
Concrete resists squeezing due to compressive strength and Steel resists bending and stretching due to tensile strength. This enhance ductility, reduce long term deflections or increase the flexural capacity for beams.
Reinforced concrete acts as a composite material inside another where steel bars provide the reinforcement to the concrete.
Usually TMT Steel bars are used which are firmly anchored inside the concrete without the risk of slipping. We use steel because it prevents excessive cracking resulting from shrinkage or temperature variation (hot and cold temperature) . Lateral reinforcement as ties and stirrups are used to provide resistance to principal tensile stresses resulting from shear resistance.
Thickness: RCC thickness depends as per design requirements.
Concrete Ratio: It can be nominal mix or design mix, depends on site requirements.
Unit: Cubic Meter (Cum)

Remote Sensing
Remote that means something which is not exactly in contact or in physical contact something which is far away. The far away could be something which is slightly away or even very far away & sensing the second word sensing means getting information getting data, getting any input the input could be something like temperature, pressure, a photograph.
o Possible to monitor any anthropogenic or natural changes in the landscape
