Differentiate between plain and reinforced concrete. Among these to which one gives more strength? It is almost twice as much concrete is used throughout the world than all other building materials combined use. To resolve this critical issue by reinforcing steel, by casting wet concrete around strong steel bars.
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.

Its mostly used as a base for footings or the base for ground floor. The Mixing ratio depends upon the grade that you want. PCC is mostly M, so the ratio would be One part of cement, two parts of sand and four parts of Aggregate.
In its simplest form, concrete is a mixture of paste and aggregates. Cement is actually an ingredient of concrete. It is the fine powder that, when mixed with water, sand, and gravel or crushed stone fine and coarse aggregate , forms the rock-like mass known as concrete. Raft foundations sometimes known as Mat Foundations are a large concrete slab which can support a number of columns and walls. The slab is spread out under the entire building or at least a large part of it which lowers the contact pressure compared to the traditionally used strip or trench footings.
Roller-compacted concrete has the same basic ingredient as conventional concrete : cement, water, and aggregates, such as gravel or crushed stone. But unlike conventional concrete , it's a drier mix—stiff enough to be compacted by vibratory rollers. Typically, RCC is constructed without joints. Consists of sand,cement, gravel and water. There is no steel bars are provided therein and hence PCCs are not good for tension.
They are good for compression. RCC- It stands for reinforced cement concrete. It is PCC expect that steel reinforcement are provided within it to carry tensile load as well as compression.
