PCC in construction refers to Plain Cement Concrete, which is used as a preparatory base for laying RCC footing. Though PCC is also concrete, this is lean in nature, the ratio being 1:4:8. The compressive strength achieved with this mix is normally 7.5kN/sq.mm.
cement fine aggregates and course aggregates and water for the hydration of cement are the main component of plain cement concrete. and for RCC M-S bars are used with these component.
A plain concrete with a large ratio aggregate to cement than structural concrete. It is used for filling and not structural duties

Concrete actually contains cement as well as sand and gravel. We say "cement concrete" because cement is an ingredient in concrete. And because the cement is what binds together the sand and gravel that make up the concrete.
Aggregate, Ordinary Portland Cement, sand, water
RCC is Reinforced Cement Concrete. PCC is Plain Cement Concrete. The main difference is that PCC has no reinforcement in it.

Ordinary Portland cement is suitable. As per IRC 21, Portland Pozzolana Cement is limited for Plain Concrete only.
cement fine aggregates and course aggregates and water for the hydration of cement are the main component of plain cement concrete. and for RCC M-S bars are used with these component.
For plain cement concrete, the aggregate used is of size 20 mm. For RCC structures, it is 40mm and for roads, it is 80mm

1:2:4
No, a 60 pound bag of cement does not weigh the same when it is turned into dried concrete. Once mixed with water and set, the weight of the dried concrete will be slightly more than the original weight of the bag of cement due to the water and other additives in the mixture.
sand=2*Weight of Cement water=cement/2
PCC is plain cement concrete. It consists of cement, sand, aggregates and water. It is good at resisting compression. RCC is reinforced cement concrete. It consists of cement, steel, aggregate and water. It is good at resisting tensile stresses also.
6'' thick sand filling, then 9'' thick plain cement concrete 1:4:8 [ ratio] then top layer of Plain cement concrete 1:1.5:3 mixed with concrete mixer. proper vibrator should be used. expansion joint should be after 2.5mts to 3mts alternatively of 12 mm wide and filled with the mixer of hot bitumen sand mixed. by: m.s.chaudhary [civil engineer]
