Kamdhenu Cement

After being introduced in 2002, Kamdhenu cement quickly saw great success. Modern production facilities and fully-equipped labs are available at Kamdhenu, an ISO 9001:2008 recognized business. The group’s total annual manufacturing capacity is now at 1.5 million tones, but that capacity will soon increase to 3 million tones.

Our high-quality product is on par with the industry’s top suppliers and is appropriate for all kinds of heavy-duty construction, such as High rise buildings, bridges, factories, canals, dams, etc.

One of the most crucial construction materials, cement, is a binding agent that sets and hardens to cling to structural components like stones, bricks, tiles, etc. An extremely fine powdered substance known as cement is often composed of calcium, silicon, aluminum, and iron ore; however, it can also contain other materials, including shells, chalk, marl, shale, clay, blast, etc.

In cement production facilities, the raw materials are transformed and heated to create a rock-hard substance, which is then crushed into a fine powder to be sold. When cement and water are combined, a chemical reaction occurs that creates a paste that sets and hardens to bond the various construction ingredients together.

A crucial component of the urban infrastructure is cement. It is used to bind the construction blocks together to secure the infrastructure and to manufacture mortar and concrete. Cement is formed of concrete, water, and lime aggregate, whereas cement is built of concrete, water, sand, and gravel blended in certain quantities.

Both of these are utilized to create beautiful patterns, fill or seal any gaps, and bind pebbles, stones, bricks, and other construction components.

Types of Cement

Ordinary Portland Cement (OPC)

The hydraulic binding substance known as “ordinary Portland cement” is made by combining Portland cement clinker, blended ingredients, and the proper quantity of gypsum. The usage of OPC in pre-stress concrete structures, including high-rise buildings, foundation systems, bridge and dam structures, industrial pavements, and nuclear containment structures, has been mandated by the Bureau of Indian Standards (BIS).

Portland Pozzolana Cement (PPC)

By combining OPC with pozzolanic substances such as silica, volcanic ash, fly ash, etc., Portland Pozzolana Cement is created. Given its many uses in the building sector, PPC is thought to be the product of the future. They are appropriate for usage in challenging environmental circumstances. They may be used with confidence to build hydraulic structures, masonry mortars, and maritime constructions.

Portland Slag Cement (PSC)

When granulated blast furnace slag is ground to a specified fineness, slag cement, a block of hydraulic cement is created and used to replace a portion of Portland cement. It is an iron blast furnace byproduct that has been recovered for industrial use. When molten slag from an iron blast furnace is redirected, it is quickly cooled, creating glassy particles when ground into cement fineness.

Manufacturing Process

We consider our offerings to be the foundation of a thriving, successful economic future. As a result, Kamdhenu cement is produced using the latest technology and superior raw ingredients. The primary raw ingredients needed to create an Ordinary Portland Cement Clinker are limestone, clay, pet coke, also known as coke breeze, and iron ore.
In a ball mill, a mixture of 70–80% limestone, 10-15% clay, 2–4% iron ore, and 8–10% pet coke is pulverized into a fine powder. The powder, sometimes referred to as the raw mix, is sent to blending silos, where it is mixed to create a mix of consistent quality. After being examined, the raw mixture is sent to a storage silo, where it is charged via a rotary feeder into a kiln that has already been lit. It burns the charge between 1300° and 1500°C. The resultant clinker is released and kept in storage for at least seven days.
Before grinding the clinker into cement, every batch is tested. Gypsum and the clinker are crushed together in the proper amounts. Ordinary Portland Cement is the refined product obtained in this manner.

Properties of Good Cement

Involving the best cement in construction is generally desirable. Subsequently, the properties of cement should be examined. Although desirable cement properties might differ depending upon the kind of development, good cement has the following properties:
  • High strength.
  • Has great versatility.
  • Great dampness, safe.
  • Hardens easily
  • Great building material
