Over the years, Permutrade has built lasting international relationships with suppliers, customers, and shippers alike. Moving materials from where they are in excess to meet the customer demands elsewhere has allowed us entry virtually anywhere in the world. As a commodity trading company, we have grown and established a global network that spans over 100 nations with strategically located marine terminals. One of the core products we deal in is cementitious materials, which are materials used to make cement.
High Quality Branded Cement For Every Construction Need
One of the basic materials for making ready-mix concrete is cement. Whether it is in bags or required in bulk, Permutrade ensures that the quality is top-notch. We take pride in providing our customers with only high-quality and branded cement for whatever their construction needs.
Cement is a fine powder-like substance. It is obtained from the calcination of iron ore, limestone, and clay at 1,450°C. The product you get from calcination is clinker, which is mixed with gypsum and other chemicals to make cement.
Cement is a binding substance that is one of the most desirable construction materials due to its valuable properties like compressive strength and durability. It sets quickly, hardens, sticks to other materials, and holds them together.
- When mixed with fine aggregates, cement produces mortar for masonry projects.
- When mixed with sand and gravel, cement makes concrete.
Types Of Cement Commonly Used By Our Customers
Gray Ordinary Portland Cement – Mainly composed of clinker, Gray Ordinary Portland Cement is a cost-effective and high-quality building material. It meets all the appropriate physical and chemical requirements for any type of construction, including public, commercial, industrial, and residential infrastructure.
White Portland Cement – White Portland Cement is white in color. Obtaining it requires substantive modification to the manufacturing method. This cement is made from those raw materials that contain minimal iron oxide and manganese oxide. It is manufactured using China clay or kaolin clay in combination with gypsum or limestone. Customers use it in works requiring a bright white finish. Typically, it is used to create mosaics, artificial granite, sculptural casts, etc.
Masonry Cement – Masonry cement is a specially blended cement. It is mixed in fixed proportions with sand and water or inert matter like limestone to form a potent binding mortar. This type of cement is used in various works like building concrete blocks, mortar and stucco work in stonework, making road surfaces, brickwork, and many more.
Oil Well Cement – Oil-well cement is a special hydraulic cement made with gray Portland clinker. It is used for cementing work when drilling for oil wells, which itself is a highly specialized activity requiring building materials with particular characteristics. Oil-well cement sets slowly due to the presence of organic retarder. It is also manageable even at high temperatures and pressures. These features make it an appropriate choice of building material in drilling oil wells.
Blended Cement – As the name suggests, blended cement is a mix of Ordinary Portland Cement with additives. The additives include fly ash, silica fume, slag, hydrated lime, calcined clay, and other pozzolans (siliceous or siliceous and aluminous material). Blended cement has technical and environmental advantages. Technically, it is smoother, firmer, has lower permeability, reduces thermal stress, and sharply reduces problems related to Alkali-Silica Reaction (expansion and cracking). Environmentally, it requires little water, involves lower energy expenditure in production, uses the waste products of coal power plants and steel plants in the blend, etc.
Aggregates are materials like sand, crushed stone, and gravel that are used for making concrete, mortar, and asphalt. They account for nearly 60% to 75% of ready mix concrete’s volume. Aggregates increase the strength of concrete, make the mix compact, allow heat retention and weatherproofing capabilities.
Aggregates are used for a variety of purposes. Some of them are:
- It is a critical component in building roads, highways, parking lots, walkways, railways, and even airport runways.
- It is used as a landfilling material to lay a firm foundation for the build.
- It is used in building homes, commercial buildings, schools, bridges, etc.
- It is used for water filtration and purification, drainage, and controlling erosion.
- It is used in playing fields, golf courses, horse racing tracks, etc.
Types Of Aggregates
Crushed Stone – Crushed stones are obtained through mining rocks and then breaking or crushing them down to a smaller favored or desired size. These are usually sourced from sedimentary, igneous, or metamorphic rocks.
Manufactured Sand – Manufactured sand is obtained by breaking rocks in a specific shape or texture, all the time making sure that the product meets the project specifications as laid by the customer.
Gravel – Weathering and erosion, two natural processes that lead to the formation of gravel deposits. Gravel is used in several things like manufacturing concrete, laying down roads, décor purposes, etc.
Sand – Sand is a naturally occurring composition of mineral particles and very fine rock material. Its constitution tends to vary depending on the source. Sand is used in making roads, producing concrete, and sometimes even for sanitation purposes.
Recycled Concrete – Existing concrete is removed, broken, and crushed to the desired size and herewith, what you get is recycled concrete. Mainly it is used as a base layer in any construction. Recycled concrete forms a solid hard surface due to its compactness, and that helps the other construction materials.
Cementitious Products Offered By Permutrade
Grey Cement and Clinker – This key element of ready-mix concrete is provided in bags and bulk, ensuring its high-quality at all times.
White Cement And Clinker – This type of cement is used where the customer requires a bright or artistic finish. It, too, is provided in bags and bulk, as the case may be.
Granulated Blast Furnace Slag – Also known as GBFS, it is a by-product from the steel industry which provides characteristics like improved workability, enhanced resistance to chemicals, and hydration heat to ready-mix concrete.
Special Mortars – Based on construction requirements, special mortars are also provided to complement the building materials.
Other products – There is a global requirement for products like fly ash and gypsum to pair with the construction materials. We fulfill this requirement as well.
