Aggregate, Ordinary Portland Cement, sand, water
Ordinary Portland cement is suitable. As per IRC 21, Portland Pozzolana Cement is limited for Plain Concrete only.
Ballast, sand and cement (+water).
For plain cement concrete, the aggregate used is of size 20 mm. For RCC structures, it is 40mm and for roads, it is 80mm

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]

cement
RCC is Reinforced Cement Concrete. PCC is Plain Cement Concrete. The main difference is that PCC has no reinforcement in it.
cement aggregates water
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.
Ordinary Portland cement is suitable. As per IRC 21, Portland Pozzolana Cement is limited for Plain Concrete only.
water amd cement
Ballast, sand and cement (+water).
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
A plain concrete with a large ratio aggregate to cement than structural concrete. It is used for filling and not structural duties
