What is mean by pcc in civil engineering?
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.
What are the components of concrete?
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.
What is dry lean concrete?
A plain concrete with a large ratio aggregate to cement than structural concrete. It is used for filling and not structural duties
What is the meaning of cement concrete of grade-m150?
the M150 grade concrete is today's hardest concrete and it has a optimal water composition of 0.18 to 0.28 percent . there is no composition for this concrete it is derived through experiments . used in very heavy structures . it has not used in india .
What is cement concrete?
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.
What are the ingredients of plain cement concrete?
Aggregate, Ordinary Portland Cement, sand, water
What is PCC and RCC?
RCC is Reinforced Cement Concrete. PCC is Plain Cement Concrete. The main difference is that PCC has no reinforcement in it.

How much sand and aggregate required 1 cubic meter of plain concrete cement?
For plain cement concrete, the aggregate used is of size 20 mm. For RCC structures, it is 40mm and for roads, it is 80mm
What is dry lean concrete?
A plain concrete with a large ratio aggregate to cement than structural concrete. It is used for filling and not structural duties
What is ratio of plain cement concrete 1 is-to 2 is-to 4 in plum concrete for road works?
1:2:4

Difference between rcc and pcc?
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.
Method of laying cement concrete road?
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]
