Which is better OPC or PCC?

PCC gives comparable strength and durability like OPC. The basic difference between them is in the manufacturing technology. Only 65% to 80% of clinker is required to produce PCC while 95% of clinker is required to produce OPC. As a result, PCC is gaining popularity worldwide due to its environmental significance.

What is Cem concrete?

Types of Cement – CEM For general construction use only types I and II are relevant. CEM I is pure (100%) OPC (Ordinary Portland Cement) CEM II is a mixture of OPC and additives such as fly ash, slag or limestone, up to a maximum additive content of 35%. CEM III is a mixture of OPC and blast furnace slag.

What is CEM II AL?

CEM II cement is a high quality general purpose cement and is suitable for most applications as listed below. The product has been specifically designed to reduce the carbon intensity of cement production.

What is Type II cement?

Type II is a moderate sulfate resistant cement, important when concrete is cast against soil that has moderate sulfate levels, but irrelevant to concrete countertops. Type III is a high early strength cement.

Is OPC better than PPC?

PPC has higher strength than OPC over a longer period of time. Generates more heat than PPC in hydration reaction which makes it less suitable for mass casting. It has a slow hydration process and thus generates less heat than OPC. Less durable in aggressive weather.

Which grade of cement is best for construction?

OPC 53 grade cement
OPC 53 grade cement is the most preferred building and construction material for projects that require high tensile strength. You can choose to buy OPC 53 grade cement online as it has the grinding of clinkers to the maximum extent and this cement grade is finer than grade 43.

What does CEM1 mean?

Put SIMPLY, a CEM1 mix contains 100% cement. A CEM2 mix is up to 35% cement replacement, (therefore, contains 65% cement). A CEM3 is up to 55% cement replacement, (therefore, contains 45% cement). Please note: These percentages refer to cement replacement referred to as ggbs / slag / PBF.

Which cement is best for foundation?

Portland Pozzolana Cement
Which type of cement is best for constructing the foundation? The foundation carries the load of the construction and hence needs to be strong and durable. Portland Pozzolana Cement (PPC) is the ideal cement to be used as it hydrates slowly and gives high final strength.

What’s the difference between CEM1 and cem2 cement?

This is because to understand cement, you need to understand the different grades. For example, a CEM1 mix contains 100% cement, whereas a CEM2 mix is up to 35% cement replacement, (i.e. it only contains 65% cement) and a CEM3 is up to 55% cement replacement, (i.e. it only contains 45% cement).

What kind of slag is used in CeM II?

CEM II is a mixture of OPC and additives such as fly ash, slag or limestone, up to a maximum additive content of 35%. CEM III is a mixture of OPC and blast furnace slag. There are three types of CEM III: A, B and C. A contains the least slag at 40%, C contains the most at 90%.

What’s the difference between GE and CEM cement?

Comparison w as done betw een the two types of cement co ncretes having same character istic strength. with the passage of time. Since water per meability of concrete is proportional to this dep th of penetration, it signifies that concrete permeability decreases with a ge.
