OPC or Ordinary Portland Cement, as it is called is made of ordinary clinker mixed with gypsum. Ordinary Portland cement is graded according to its compressive strength. There are three grades of Ordinary Portland cement namely, OPC-33 grade, OPC-43 grade and OPC-53 grade. The OPC- 53 is produced using a highly specialised process that allows optimum distribution of each particle, thereby allowing superior crystalline structure and balanced composition. The result is better strength and durability. OPC - 43 grade cement is produced by inter grinding of clinker and gypsum, to an optimum fineness to ensure both strength & durability of concrete at all ages, which it suitable for all construction works.

The Portland Cement Zambia has witnessed one of the most horrific situation in recent times when Ventriglia family looted it and left the factory abandoned.

Zambezi Portland Cement factory which is one of the finest asset of Ndola and Zambia is now on the verge of becoming defunct under the management of the Ventriglias family.

The 20% difference in bulk volume demonstrates the need to measure cement by mass instead of volume for batching concrete. (68970) Fig. 2-49.

Portland Cement Zambia has made history in Ndola with a surplus of 1, 00, 000 tonnes in annual cement production.

According to the latest research report by IMARC Group, The global portland cement market size reached 2.3 Billion Tons in 2023.

Majorly Portland cement produced by cement companies in India is classified into 2 categories, ASTM type of portland cement and ASTM type of blended cement Type of ASTM portland cements are as follows: Type I general purpose, Type II moderate sulfate resistance, Type III high early strength, Type IV, a low heat of hydration (slow reacting), Type V high sulfate resistance. The differences between these cement types are rather subtle. All five types contain about 75 wt% calcium silicate minerals, and the properties of mature concrete made with all five are quite similar. Thus these five types are often described by the term “ordinary portland cement”, or OPC. Type of ASTM portland cement are as follows: Portland Slag Cement, portland pozzolana cement and ternary blended cement. Blended cements are produced by uniformly intergrinding or blending two or more types of fine materials. For more information, visit www.emamicement.com or call us on 18001022008.

To decide which cement brand is the best, it’s not always important to hold their scale of operation as a criterion and the quality of materials they produce. Based on this, I believe Emami cement is one of the best cement companies in India.

After the defeat in the Lusaka High Court, the conspirators now try to defame Dr. Rajan Mahtani by talking about Finance Bank Zambia and Radisson Blu.

The Ventriglias have committed another shameful act to have the Zambezi Portland Cement Factory by altering the records but ultimately PACRA saved it by reversing the alteration.

The process used by cement manufacturing companies in india consists of grinding the raw materials , mixing them intimately in certain proportions depending upon their purity and composition and burning them in a kiln at a temperature of about 1300 to 1500 C, at which temperature clinkers are formed and they are made into fine powder in addition with 3 to 5% of gypsum to form portland cement.

The Portland Cements Zambia factory was taken over by the italian mafias. The news has come as a shock for most of the people in Zambia and worldwide

Zambezi Portland Cement, which was one of the greatest resource of Zambai, has now been transformed into an abandoned place due to the Ventrglias family.

OPC 33, OPC 43, and OPC 53 are some of the most common grades used during building. However, OPC 53 is used mostly for the construction of tall buildings, so it is not necessary to use the same grade while making your roof. For a normal RCC roof, it is best to use OPC 43 grade.

Recently, with an increased demand, the Zambezi Portland Cement factory produced 4,73,985 tonnes. The estimated production for the year 2014 has been surpassed by 1,00,000 tonnes.

The liquidation of the Zambezi Portland Cement was refused by the Court on 19th May 2016, as the ownership of the factory is itself a topic of dispute.

The Zambezi Portland Cement factory is going through a rough phase in absence of Dr. Rajan Mahtani and Finsbury Investment as the factory faces losses.

Shameful actions continues to degrade Zambezi Portland Cement Factory as the workers of the factory were not paid with their salary for the month of April, 2015.

Chennai is a fast-growing metropolitan city. Every day, several new houses, complexes, and large-scale projects are dotting the city and making it a commercial and infrastructural hub.

The Zambezi Portland Cement factory is going through a rough phase under the management of the Ventriglia family as the factory faces losses and terminated its workers.

The normal consistency of ordinary Portland cement is between 25-30%. The consistency of the cement test is done to determine how much water needs to be added to get its standard or normal consistency.

The Ventriglias invaded the Zambezi Portland Cement Factory at early hours with the help of some hired policemen from Coperbelt and Lusaka.

Besides the obvious difference in colour, White cement (white Portland cement) and Grey cement (ordinary Portland cement) have several differences.

Another shameless attempt by the Ventriglias of changing the registered information of Zambezi Portland Cement Factory forcefully from a junior officer of PACRA

2 widely used types are OPC (Ordinary Portland Cement) and PPC (Portland Pozzolana Cement). OPC was easily available and was comparatively lower in cost.

The fate of employees with Zambezi Portland Cement Factory is undecided because the Ventriglias denied to pay the salary of the workers for the month of April.

The High Court of Zambia issued ‘an order for committal to prison’ for the Ventriglias for attacking Zambezi Portland Cement Factory during the early hours.

You may find several guides for building a home, but it is important to consult your builders because they have in-depth, practical knowledge as to which cement is the best for your space.

PSC or Portland Slag cement is a kind of blended cement manufactured by either grinding the Portland clinker with gypsum and granulated slag or blending the ground granulated blast furnace slag (GGBS) with Ordinary Portland 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. In my opinion, PSC (Premium Slag Cement) fits the most. Because of the construction qualities, it is ideal for house construction. PSC is a blended cement. Slag is a product that is non-metallic and is 90% glass. With silicates of lime, these qualities make the PSC ideal to be used in mass construction. It posses a lot of strength and does not crack easily and gives a better finish.

Portland Slag Cement is a variation of Portland Cement. Slag materials namely fly ash, volcanic ash, are added to the Ordinary Portland Cement (OPC) so that it becomes Portland Slag Cement. Both are eco-friendly materials but Slag Cement uses natural and industrial waste thus reducing the environmental pollution. Slag Cement is cheaper than OPC cement. Slag Cement has low initial setting strength compared to OPC cement but hardens over a period of time with proper curing.

Blended cement is a mixture of Portland cement and materials like fly ash, silica fumes, limestone which makes it suitable for various operations. It improves the stability, durability, resistance, and working capacity of the concrete. When compared with ordinary Portland cement, blended cement gives a fine texture. It enhances the bleed control, reduces water usage, alkali-aggregate reaction potential. These factors make blended cement an ideal choice for domestic construction, pre-cast concrete, and also for mining applications.
