What is the difference between PPC and slag cement?

The Portland Pozzolana Cement (PPC) is a kind of blended cement which is produced by either inter grinding of OPC clinker along with gypsum and pozzolanic materials in certain proportions. PSC is a blended cement. Slag is a product that is non-metallic and is 90\% glass.

Is slag cement good for construction?

Portland Slag Cement, commonly known as PSC, is blended cement. PSC has been voted as the most suitable cement for mass construction because of its low heat of hydration.

Is slag cement good for concrete?

Slag cement is most widely used in concrete, either as a separate cementitious component or as part of a blended cement. It works synergistically with portland cement to increase strength, reduce permeability, improve resistance to chemical attack and inhibit rebar corrosion.

Why Portland slag cement is used?

Portland slag cement is nowadays commonly used in general civil engineering construction works and is mainly preferred for construction of main structures and in coastal areas where excessive amount of chloride and sulphate are present. It is most useful in massive construction projects such as dams.

Is slag cement cheaper than Portland cement?

Slag is similar to fly ash in that it is finer than standard Portland cement and is also cheaper as it is a process byproduct.

Why can we use more slag cement to replace Portland cement?

Slag cement provides higher levels of compressive strength in concrete when compared with ordinary portland cement (OPC) concrete of equal cementitious materials content.

Is slag cement cheaper than portland cement?

Why can we use more slag cement to replace portland cement?

Why is slag good for concrete?

The use of slag in concrete has several benefits, including reduced energy, reduced greenhouse gas emissions, and reduced use of raw materials. – Granulated blast-furnace slag (GBFS)—The glassy granular material formed when molten blast-furnace slag is rapidly chilled, as by immersion in water. …

What are the advantages of Portland slag cement over ordinary cement?

The gypsum will be added as the usual ratio, like the manufacturing of OPC. The main advantage of Portland slag cement is the effort of manufacturing this cement is much less than the Ordinary Portland cement because the slag is a waste material.

What is the composition of slag cement?

It is created with a blend of 45- 50\% slag, 45\% & 50\% clinker, and 3-5\% gypsum. Portland slag cement is the most suitable cement for concrete paths, mass concrete uses, structures and bases, Pre-cast concrete, concrete open to seawater and oceanic use.

What are the uses of Portland pozzolana cement?

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