Portland Cement Supplier

Cement hydration (adding water) leads to a complex chemical reaction that is accompanied by thermal expansion. The UK revised standards for Portland Cements that are commonly used for repairs are as follows:

1. Portland cement–grade 42.5; based on BS 12: 1991 (CEM 1)
2. Portland cement – grade 52.5; based on BS 12: 1991
3. Portland cement – grade 42.5 R; based on BS 12: 1991
4. Sulfate-resisting Portland Cement-grade 42.5; based on BS 4027: 1991
5. Building cement: BS 5224: 1995-ENV 413-1

The letter “R” indicates high initial resistance.

Revised versions are mainly related to testing methods and specific terms, and they aim to comply with the European Cement Standard (ENV 197-1). Minor changes to the composition are also introduced. If the required cement is Ordinary Portland cement, then Portland cement grade 42.5 based on BS12: 1991 is required.

If Portland cement is required with a fast hardening, then either Ordinary Portland cement grade 52.5, based on BS12: 1991, or Portland Cement grade 42.5 R, based on BS12: 1991, are advised.

The above types of cement are almost exclusively for repairing. In 1990 and 1991, a complete correction version of BS 5328: 1991 was issued for concrete in four sections.

Portland cement mainly consists of calcium silicate and calcium aluminate compounds. The amount of calcium silicates is always between 55% and 85%.

Also, the amount of tricalcium aluminate is between 7 to 12% and iron hydroxide is also between 6 to 10%.

Cement is made from burning gypsum and clay mixture in a rotary kiln under high temperatures.

Clinker is the main material, and gypsum stone is added to control sulfur, which, according to the BS 12, is equal to 3.5%. When examining the possibility of a sulfate attack on concrete or mortar, Portland Cement containing sulfate is of great importance. In the following, we will present further information on the reaction between different sulfate groups (calcium, magnesium, and ammonium).

Iranian Portland cement suppliers are exporting Cement and Clinker to at least 28 foreign countries.

During the first five months of the Iranian year (March-Sep 2018), the customs statistics tables show that Iranian Portland cement suppliers exported 7 million and 539,422 tons of cement chain by 8 percent enhancement from the same period last year.

The value of cement exported during the above period was $ 270.4 million, up 7 percent from the same period last year. Iranian Portland cement suppliers aim for new markets for their products through targeted marketing and joint production.

Portland cement supplier is striving and planning for long-term sustainability in the target markets. Furthermore, he is adhering to the professional ethics of trade While considering the export of final products, deepening economic connections, joint investments for the construction of Asian clinker units, and exploiting the mines of target countries.
