Which cement is mostly used in RCC structure?

OPC 53-Grade- It is mostly used in RCC structures, buildings, pre-stressed concreting, 53 Grade attains 27 Mpa in 7days compared to 23 Mpa by 43-grade cement and achieves a final compression strength of 53 Megapascals in 28 days.

Which cement is best for RCC concrete?

OPC is the best for house construction in India. Generally, OPC 53 Grade cement is suitable for all RCC structures like footing, column, beam, and slabs, where ever initial and ultimate strength is the major structural requirement.

Which cement is best for RCC OPC or PPC?

PPC has a lower heat of hydration and it is prone to fewer cracks compared to OPC. PPC has lower strength than OPC but PPC provides better workability and finishing than OPC. PPC provides greater resistance to chemicals.

Which is the main material used for RCC?

Following four materials are required for making R.C.C.: 1. Cement 2. Aggregates 3. Steel 4.

Which is better OPC 43 and OPC 53?

OPC 53 sets quicker than OPC 43 and has a quite low initial setting time. It is used in structures where rapid strength gain is required like large load bearing structures like bridges, huge buildings, etc. OPC 43 on the other hand doesn't set so quickly and has a normal initial and final setting time.

Where is OPC and PPC cement used?

Use of PPC and OPC

They can be reliably utilized in the construction of marine structures, masonry mortars and plastering, hydraulic structures. Besides, they are popularly used in mass concreting works, such as dykes, sewage pipes, dams, etc. PPC is also employed in all other applications where OPC is used.

Can we use PPC cement for RCC work?

OPC cement can also be recommended for the construction of columns, beams, etc. On the other hand, PPC cement is made up of 75-77% cement clinker, 20% flyash and 3-5% gypsum. They are commonly used for small residential construction. PPC is recommended for brick masonry, plastering, tiling and waterproofing works.

What is RCC cement?

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.

Why cement is used in RCC?

RCC stands for reinforced cement concrete. In the tension Concrete is week but it is excellent in compression. Steel is really good in tension. Steel is utilised as a reinforcing material to enhance the tensile strength of concrete and the coefficient of linear expansion for both steel and concrete is same.

Why is concrete used in RCC concrete?

Advantages of Reinforced Cement Concrete

Structures made from reinforced concrete are stable and durable. It possesses high compressive and high tensile strengths. It is economical, and the maintenance cost is almost ignorable. R.C.C has the least chances of buckling and rusting.

Which cement is best OPC or PSC?

PSC has the following advantages over OPC. Due to presence of slag, PSC is usually lighter in colour than OPC. The words Portland Slag Cement is written on all PSC cement bags. Further, due to its improved properties, PSC is generally priced higher than OPC in the market.

Which cement is best for roof?

The best roof cement in India includes OPC53 grade and PPC cement, brand name Ambuja plus Roof Special Cement, ACC Gold, ACC F2R, Shri Roofon Concrete Master, Ramco Supercrat Cement.

What is PPC and OPC cement?

PPC (Portland Pozzolana Cement) is a variant of OPC (Ordinary Portland Cement.) These two type of cement differs from each other in terms of component, strength, heat generation, the percentage of several components, durability, grades, cost, eco-friendly nature, application, setting time, curing period etc.

Which cement brand is best for RCC slab?

OPC 53 and PPC ( Portland pozzolana cement) of all brand are the best cement for rcc roof slab construction in india,bihar and jharkhand. It provide higher strength to rcc roof slab withstand with different types of load acting on it.

What is OPC 53 grade cement?

OPC 53 Grade cement is required to conform to BIS specification IS:12269-1987 with a designed strength for 28 days being a minimum of 53 MPa or 530 kg/sqcm. 53 Grade OPC provides high strength and durability to structures because of its optimum particle size distribution and superior crystallized structure.

What are ingredients of RCC?

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.

What is the ratio of cement water and sand in RCC?

If concrete is provided with steel bar or reinforced, the safest best mix ratio for RCC concrete is 1: 1.5: 3 (Cement, Sand, aggregate), in which one part is cement, 1.5 part is fine aggregate or sand and 3 part is coarse sand or aggregate.

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.

Why is PCC used in construction?

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 is better PSC or PPC?

PSC lessens the risk of shrinkage cracks and cracking. Strength gain is less in PPC and it is also not suitable for high performance concrete and quick concrete setting whereas PSC brings ultimate strength and excellent finish, hence PSC holds the upper hand.

Which grade of OPC is best?

OPC 53 grade Cement

OPC Cement gives high compressive strength at early ages and at 28 days. A 53 Grade cement gives up to 70 MPa strength against a minimum 53 MPa specified by BIS. So, We can also mix fly ash (at least 20% by weight of cement) in concrete as part replacement of cement at site.

Which is costly OPC or PPC?

Cost. The cost of OPC is around 300 rupees per bag which is slightly more expensive than PPC. Whereas in the case of PPC, the expensive clinker is replaced by pozzolanic Material such as fly ash hence the price of PPC is slightly less than who OPC.
