What is the advantage of PPC over OPC?

What is the advantage of PPC over OPC?

It generates less heat of hydration at a low rate than ordinary Portland cement. Reduction in permeability of PPC offers many other advantages, such as better durability than opc 53 cement.

Can we use PPC instead of OPC?

For a building slab, PPC is more widely used since it requires less care. The strength depends on design mix (the water cement and aggregate ratio) more than type of cement. so essentially, If you need construction to take place faster and have means for good curing, you may use OPC.

Which cement is better 43 grade or 53 grade?

OPC 43 Grade cement attains a minimum compression strength of 43 MPa in 28 days of setting as compared to OPC 53 which attains a strenth of 53 MPa in the same time. Initial Strength: … 53 Grade attains a minimum strength of 27 MPa in 3 days as compared to only 23 MPa achieved by 43 grade cement.

Which cement is best for roof?

It is used majorly for wall plastering works, Non-RCC structures, pathways etc. 43-grade cement attains a compression strength of 43 Mpa (megapascals) in 28 days of setting. Make sure that your 43 cement brand adheres to IS 12269 standard code.

Which cement is best in India?

Used in hydraulic structures, marine structures, construction near the sea shore, dam construction etc. Used in pre-stressed and post-tensioned concrete members. As it gives better surface finish, it is used in decorative and art structures.

What is the basic difference between OPC and PPC?

PPC is prepared by adding Pozzolanic materials to OPC. So, the main components are OPC clinker, gypsum and pozzolanic materials (15~35%) which includes calcined clay, volcanic ash, fly ash or silica fumes. PPC has higher strength than OPC over a longer period of time.

Does PPC cement have grade?

PPC does not have any grade, only OPC have a grade.

Which cement is best for RCC slab?

OPC 53 Grade cement is recommended in all RCC structures like footing, column, beam and slabs, where ever initial and ultimate strength is the major structural requirement.

Which cement is used for plastering?

There are three main Cement Grades from which you can choose. These are Ordinary Portland Cement (OPC), Portland Slag Cement (PSC) and Portland Pozzolana Cement (PPC) available in the market. OPC is available in two grades — 43 and 53. Both grades are considered best for plastering work.

How many types of cement are there?

There are six different types of cement with specific defining behaviours and chemical compositions. Below we look at each type and what makes them unique. Type I; Ordinary Portland Cement (OPC). This is a general purpose cement with no special properties.

What is OPC & PPC cement?

Ordinary Portland Cement (OPC) is the most common cement used in the world because of the abundance and low cost to produce it. 2. Portland Pozzolana Cement (PPC) is a variation of OPC which includes a mixture of a pozzuolanic material which can increase the strength of the concrete and reduce the amount of OPC used.

Which is costlier OPC or PPC?

It is less costly as compared to OPC because costlier cement clinkers are replaced by cheaper pozzolana material. 1 bag of PPC (50 kg) gives more volume of mortar than OPC bag as the pozzolanic material is finer and it has lower density.

Which grade of cement is used for slab?

The high strength concrete includes M60 and M80 grades. Generally M10 and M15 grades of concrete are used for leveling course, and bedding for footings. Standard concrete and concrete of grade M20 is applicable for Reinforced Cement Concrete (RCC) works for slabs, beams, columns and so on.

What are the types of cement and their uses?

The minimum period for curing concrete to attain maximum strength is 28 Days. From the above graph, it is clear that concrete attains 50% of its design strength when it cured for 3-7 Days. 75% of Compressive strength achieved in 14 days and 90% of strength by 28 days as time goes on the strength increase gradually.

What is the strength of PPC cement?

It protects concrete against alkali-aggregate reaction. The minimum compressive strength of PPC after 28 days, as prescribed by BIS is 33 MPa or 330 kg / Cm2. However, the ultimate, long-term strength of PPC is better compared to OPC 53.

What is the use of clinker?

Portland cement clinker is ground to a fine powder and used as the binder in many cement products. A little gypsum is sometimes added. It may also be combined with other active ingredients or chemical admixtures to produce other types of cement including: ground granulated blast furnace slag cement.

Why is pozzolana added to cement?

Typically pozzolans are used as cement replacements rather than cement additions. Adding pozzolans to an existing concrete mix without removing an equivalent amount of cement increases the paste content and decreases the water/cement ratio.

Which brand cement is best for plastering in India?

PCC-It stands for prestressed cement concrete. Consists of sand,cement, gravel and water. … RCC- It stands for reinforced cement concrete. It is PCC expect that steel reinforcement are provided within it to carry tensile load as well as compression.These are used in beam and column sections mainly.

What is pay per click marketing?

PPC stands for pay-per-click, a model of internet marketing in which advertisers pay a fee each time one of their ads is clicked. … It allows advertisers to bid for ad placement in a search engine's sponsored links when someone searches on a keyword that is related to their business offering.

What is composite cement?

Composite cement is a mixture of high quality clinker (IS:16353-2015), fly ash (IS:3812 (Part 1) – 2013), granulated slag (IS:12089-1987) and gypsum.

What does 33 43 and 53 grades of cement mean?

33 43 53 are the three grades of cement very widely used in the Construction industry. The characteristic compressive strength of the three grades of cement after careful curing for 28days should not be less than 33MPa 43 MPa and 53 MPa.

Can we use PPC for slab?

Better for use in slabs : PPC or OPC. OPC (m53) attains strength in a shorter time, while PPC (m43) takes longer. … For a building slab, PPC is more widely used since it requires less care. The strength depends on design mix (the water cement and aggregate ratio) more than type of cement.

What is slag cement?

Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace.

What is meant by 43 grade cement?

Cement grade indicates the compression strength of the cement concrete after 28 days of setting. 43 Grade Cement attains compression strength of 43 Mpa (megapascals) in 28 days of setting compared to 53 Mpa attained by 53 Grade cement.

Which cement is best OPC or PPC for house construction?

PPC produces highly durable concrete as it has low water permeability compared to OPC. PPC has low initial setting strength compared to OPC but hardens over a period of time with proper curing. And PPC is cheaper also compared to OPC.

What is OPC in construction?

1.Ordinary Portland Cement (OPC) is the most common cement used in the world because of its abundance and low cost of production. 2.Portland Pozzolana Cement (PPC) is a variation of OPC that includes a mixture of a pozzuolanic material that can increase the strength of the concrete and reduce the amount of OPC used.
