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.

Which is cheaper OPC or PPC?

In these works, strength is not the major criteria. PPC has an edge on OPC as PPC has slower rate of heat of hydration. Thereby PPC is prone to less cracks & reduced shrinkage), better workability and finishing (as fly ash based cement are spherical in shape and finer in size).

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.

Why gypsum is added in cement?

Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process. Gypsum is added to control the “setting of cement”.

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.

Where is PPC cement used?

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.

Which cement is good for construction?

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.

What is PPC & OPC 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 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.

What is PPC in construction?

In relation to this, PPC refers to a form of Portland Cement which is Portland Pozzolana Cement. PPC is produced when pozzuolans are used in the mixture. Pozzuolana is a cement extender improving the strength and durability of the cement or even reducing the costs of producing concrete.

Does PPC cement have grade?

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

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 RCC and PCC?

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 PPC cement grade?

Emami Double Bull PPC is manufactured by synchronizing two-stage hydration process involving clinker and pozzolanic material, resulting in a dense, gel-like formation.

What is clinker used for?

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 do we use 53 grade cement?

Grade 53 should therefore be used only where such application is warranted for making the concrete of higher strength, where good supervision and quality assurance measures are in place and where proper precautions are taken to relieve the higher heat of hydration through a proper curing process.

How is OPC cement made?

Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.

What is OPC clinker?

A Mixture of Limestone and Clay is ground and burnt at a very high temperature to form Clinker. … The basic difference lies in the percentage of clinker used. Ordinary Portland cement (OPC) OPC, popularly known as grey cement, has 95 per cent clinker and 5 per cent gypsum and other materials.
