What is the difference between PCC and RCC?
Plain cement concrete (PCC) is a hardened mass obtained from a mixture of cement, sand, gravel, and water in definite proportions. It does not contain a steel rod. If steel is kept in the concrete then it is called Reinforced cement concrete (RCC).
What is PCC concrete ratio?
Proportioning of Plain Cement Concrete
Generally 1:2:4 or 1:3:6 mix is used.
Why PCC is done?
The main reason of providing PCC is to provide a rigid impervious bed to RCC in the foundation before starting any RCC or masonry work directly on the excavated soil, PCC is done to form a leveled surface and to avoid laying concrete on soil directly so as to avoid mixing with soil and also to prevent soil extracting
What is PCC construction?
The objective of plain cement concrete alias PCC is to arrange a firm impermeable bed to RCC in the foundation where the soil is soft and flexible. It is also known as Cement Concrete (CC) or Blinding Concrete. When, any reinforcement is not used inside the concrete, it is defined as the plain cement concrete.
What does PCC mean?
|PCC||Patient Care Component (US DHHS)|
|PCC||Plain Cement Concrete|
|PCC||Praise Christian Center (various locations)|
|PCC||Pasteur Culture Collection of Cyanobacteria|
What is Fullform PCC?
The full form of PCC is the Police Clearance Certificate. It is a legal certificate issued by a government body or police department to confirm that the applicant does not have a criminal record.
How do you calculate PCC?
Suppose we have project of making concrete pavement of area 100m2 and slab thickness of PCC is 150 mm. Now we have to calculate dry volume calculating dry volume we should multiply a cofactor 1.54 in wet volume. Mix ratio in M15 grade = 1:2:4 one part cement two part is sand and 4 part is aggregate.
What is the grade of PCC?
Concrete Grade and Mix Ratio Table
|Group||Concrete Grade||Mix Ratio|
|Ordinary Concrete||M7.5||1: 4: 8|
|M10||1: 3: 6|
|M15||1: 2: 4|
|M20||1: 1.5: 3|
How much is 1m3 of cement?
Typically, 1m3 of concrete is made up of 350Kg of cement, 700Kg of sand, 1,200Kg of chippings and 150 Litres of water.
Which grade concrete is used for PCC?
For plain cement concrete works, generally M15 is used. For reinforced concrete construction minimum M20 grade of concrete are used.
What is the ratio of RCC?
What is RCC? Why TMT Bar is required in RCC?
|Concrete Grade||Proportion of Cement: Sand: Stone pieces||Expected Compressive Strength at 28 days|
|M10||1: 3: 6||10 N/mm2 or 100 Kg/cm2|
|M15||1: 2: 4||15 N/mm2 or 150 Kg/cm2|
|M20||1: 1.5: 3||20 N/mm2 or 200 Kg/cm2|
|M25||1: 1: 2||25 N/mm2 or 250 Kg/cm2|
Where is RCC used?
Reinforced concrete is being used for the construction of foundations to the rooftops of buildings, in the construction of highways roads traffic, precast structures, floating structures, and hydro-power tunnels, irrigation canals, drains, and all other conceivable structures.
What is M20 grade?
M20 signifies mixture of cement, sand and aggregate which are prepared in such a manner that a cement concrete cube of size 15 cm x 15 cm x 15 cm is formed with characteristic strength (fck) of 20mpa while examining it after being cured for 28 days.
What is the minimum grade of footing PCC footing concrete?
PCC is only a leveling course and a lean mix, say 1:4:8 may be sufficient. Dear Er, You can use M10 (means 100kg/cm2 = 1000t/m2) as leveling coarse over uneven rock, but little wider (400mm extra in width and length of footing size).
