What is RCC and PCC?
Reinforced cement concrete (RCC) is PCC + reinforcement. The reinforcement is generally steel bars bent and laid into the desired shape and orientation. The reinforcement can be both tensile or compressive reinforcement depending upon the situation. However, mostly both are used in any structural member.
What is PCC and RCC in concrete?
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 the meaning of RCC?
Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility.
What is difference between RCC and concrete?
The Advantages & Disadvantages of Reinforced Concrete
Reinforced concrete, or reinforced cement concrete (RCC), is actually very similar to PCC in terms of materials used. The one big difference in its composition is the addition of steel rebar.
What is PCC and its uses?
Plain cement concrete is the mixture of cement, fine aggregate(sand) and coarse aggregate without steel. PCC is an important component of a building which is laid on the soil surface to avoid direct contact of reinforcement of concrete with soil and water.
Difference Between PCC (Plain Cement Concrete)
Where is RCC used?
It is used for paving in airports, roads and high traffic areas. It is used for constructing various structures like water tanks, dams, bins, silos, bunkers, bridges, retaining walls, underwater structures, towers, multi-storey buildings, docks and harbours.
Which is better PCC or RCC?
In terms of strength, naturally, RCC is stronger because the reinforcement helps in load-carrying capacity. PCC is weaker and is only used for layering surfaces like plastering work or flooring and most importantly in the layering if excavation to cast footings.
Is PCC waterproof?
The surface course is the layer in contact with traffic loads and is made of PCC. It provides characteristics such as friction (see Figure 3), smoothness, noise control and drainage. In addition, it serves as a waterproofing layer to the underlying base, subbase and subgrade.
What is CC in civil?
Concrete cloth (CC) is a unique proprietary material. It has a very wide range of applications throughout the building & civil engineering industry. Concrete cloth is a flexible; cement impregnated fabric that hardens when hydrated to form a thin, durable, water & fire proof concrete layer.
Why is RCC used?
It is used for the construction of large infrastructure projects like Bridges, Retaining walls, Docks, and harbors, Underwater structures. RCC is also used for precast element casting like Railway sleepers, Electric poles. It is used for constructing tall structures like Multistory buildings, Chimneys, Towers.
Why steel is used in RCC?
It is because the two materials bond together very well with no slippage and thus act together as one unit in resisting the applied loads, apart from few other important properties of steel. The tensile strength of steel is approximately equal to 100 – 140 times the tensile strength of plain concrete mix.
What is RCC slab?
A Reinforced Concrete Slab is the one of the most important component in a building. It is a structural element of modern buildings. Slabs are supported on Columns and Beams.
What is RCC road?
Roller compacted concrete (RCC) is a tough, durable type of concrete pavement that is well suited for heavy industrial applications, as well as low-speed roads and arterial roads. Roller compacted concrete draws its name from the construction practices used to place and finish the material.
What is PCC slab?
PCC full form is plain cement concrete. It is a mixture of cement, sand, aggregate, and water without reinforcement. PCC Concrete is spread on the soil surface before concreting maid structure to avoid direct contact of reinforcement of concrete with soil and water.
What is PCC thickness?
The Thickness of PCC: The thickness of PCC is normally 50mm over Brick Flat Soling (BFS). If you don't use BFS below PCC then the thickness should be 75¬mm. When the PCC is used in car parking area then the thickness should be 75mmover BFS.
What is M20 grade concrete?
For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix. These grade of concrete is converted into various mix proportions. For example, for M20 concrete, mix proportion will be 1:1.5:3 for cement:sand:coarse aggregates.
What is OPC cement?
Ordinary Portland cement (simply called ordinary cement) refers to the hydraulic binding material ground by mixing Portland cement clinker, 6% ~ 15% blended materials, and appropriate amount of gypsum, code-named P• O.
What is the ratio for RCC and PCC structure?
1:4:8 (m7. 5), 1:3:6 (m10) and 1:2:5 (m15) is concrete mix ratio used for floor, PCC & none RCC structure. Best concrete mix ratio for general domestic jobs are 1:2:4, means 1 part of cement mix with 2 parts of sand or fine aggregate to 4 parts of Gravel or coarse aggregate.
Why do we use PCC?
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 ...
Which mm rod is used for roof?
bars or 8 mm or 10 mm tor-steel bars are generally used.
How much steel is 1m3 of concrete?
Minimum quantity of steel required for 1 m3
concrete beam is 1%, now 1% of 1m3
= 0.01 m3
, and we know that 1m3
steel weight is 7850 Kg, so weight of 0.01 m3
steel = 0.01 × 7850 = 78.50 kg, so minimum quantity of steel required for 1m3
concrete beam is 78.50 Kg.
Which steel is used in RCC?
Mild Steel Bars are used in RCC for beam, slabs etc. The Tensile Strength is upto 40000 psi. Mild Steel Bars does not bond well with concrete and it is poor in quality that is why it is used in small projects with budget constraint.
Which is better RCC wall or brick wall?
Brick and mortar structures have the deficit of a stronger core and bond that can withstand strong forces, therefore making them less reliable. RCC constructions are therefore more durable and reliable for life and property.
