PCC is Plain Cement Conrete!  Water cement ratio is the amount of water added to cement.  It depends upon grade of concrete for example m20 -0.55,m25-0.5.
It is directly propotional to workability and inversely to strength.

After the process of excavation, laying of plain cement concrete that is PCC is done. A layer of 4 inches was made in such a manner that it was not mixed with the soil. It provides a solid base for the raft foundation and a mix of 1:5:10 that is, 1 part of cement to 5 parts of fine aggregates and 10 parts of coarse aggregates by volume were used in it. Plain concrete is vibrated to achieve full compaction. Concrete placed below ground should be protected from falling earth during and after placing. Concrete placed in ground containing deleterious substances should be kept free from contact with such a ground and with water draining there from during placing and for a period of seven days. When joint in a layer of concrete are unavoidable, and end is sloped at an angle of 30 and junctions of different layers break joint in laying upper layer of concrete. The lower surface is made rough and clean watered before upper layer is laid.

Pcc - Primary cement concrete, Means Lean Concrete. It is most important thing. It should be done before Rafting, Brickwork, or c c work. it is too necessary for RCC ,Masonry Brick work Etc.....

P.C.C means Plain Cement Concrete. When any foundatin is build on the earth level or below earth level, it needs a strong platfrom to stand foundation so P.C.C is done.

1)PCC means Plain Cement Concrete.
2) It acts as a bed on which footing rests & also to distribute the load uniformily.
3) Since the footing can not be rested directly on soil.

1.Pcc stands for Plain Cement Concrete.

2.It is used below foundation to make the surface hard on which foundation rest.

3 The main used of PCC to make surface hard and then laid a waterproofing layer so it also water resistant base for foundation.

1. plain cement concrete
2. water cement ratio is 0.45
3.it is used to make like slab,terrace

The answer which was given by Mr G. Sindhars 3 point is wrong i think because pcc have only compression strength and in condition of slab we need tensile strength so we provided steel and we know that concrete have 10% tensile strength of compression so we cant use pcc in slab.

the only reason PCC is used below footing is to avoid the base of footing to come into direct contact with the sub surface.

PCC means Plain Cement Concrete. w/c ratio depends on grade of concrete . the main purpose it is used below foundation is to successfully transmit load from superstructure to the sub surface in a balanced manner and to provide cushion between foundation and subsurface.

1- Plain Cement Concrete
2- It is water cement ratio according to Grade, as M-10(.75), -15(.65)
3- It is used to foundation, raft for compressive strength and strong platform.
4- PCC thickness is according to wet. Well it is thickness is min. 4" max 12"

PCC = Plain Cement Concrete
It is used below foundation to make plane surface over the soil or placing of footing and net of footing it also prevent direct contact of concrete to soil to absorb water from concrete.

PCC is formally known as Plain Cement Concrete which is used in the foundation before starting the structure, the structure in foundation should be used stoned for bearing the over load of super structure than brick.

PCC is known as Plain Cement Concrete, which is made up of only Cement Fine-Aggregates, Coarse-Aggregates, and Water.
PCC bed is provided below foundation because it provides uniform/ plain surface for RCC work of Foundation as well as it acts as impermeable membrane for Ground water table.

When we directly lay the foundation into the soil bed the effective depth may differ due undulations hence PCC bed is provided for a level surface.
