We first discuss cement production and special nomenclature used by cement industrialists in expressing the composition of their cement products. Advantages of PPC (Portland Pozzolana cement ) The production is economical because costly clinker is replaced by cheaper. What are the advantages and disadvantages of marble flooring? If you were where I am, I’d suggest the first and most apparent disadvantage is that it indicates that you are not familiar with the terminology we use. Advantages and Use of Ordinary portland cement It has been possible to upgrade the qualities of cement by using high-quality limestone, modern equipment, closer on line control of constituents, maintaining better particle size distribution, finer grinding and better packing. OPC has great resistance to cracking and shrinkage. Publications on the field of alkali-activated binders, state that this new material is likely to have high potential to become an alternative to Portland cement. The concrete industry has been getting beat up for the past decade over the large carbon footprint of cement, and it’s true that cement manufacturing releases a significant amount of carbon dioxide into the environment. If the percentage is exceeded, the strength of cement is reduced. Portland Pozzolana Cement (PPC) – Uses, Disadvantages & More … Portland Pozzolana Cement also commonly known as PPC cement.
