 Portland cement Type 1-325 Application

It is useable in all Reinforced concrete and Non Reinforced concrete and basically all the cases that need special specs like resistance towards striking Ions and hydration heat are not considered. Because of high primary and final resistance especially in cases that need for faster opening and transferring of formwork of concrete is proposed it is used in building concrete silos as well. Also because of high amount of Phase C3S and as a result of produced heat the cement can be used in winter mild climate and thanks to this , this kind of cement  is used cautiously in hot areas where the danger of  increasing concrete temperature exists.

Portland Slag Cement Application

Slag is the material collected on top of blast kiln of smelting iron and known as waste products of steel industry. If slag is gets cold slowly, it is crystal shape that is not consumed a lot. But if we make it cold fast, it gets amorphous or glassy that is used after milling, is applied in cement industry. While milling the slag you have to pay attention that where slag hardness is more that cement, each of them has to be milled separately and finally mix them. In Iran slag cement is divided to 3 kinds that will be said as follows:

1. Portland slag cement with less than 25% of slag
2. Portland slag anti sulfate cement with 25 to 70% of slag
3. Portland slag cement with more than 70% of slag
