Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the mid 19th century, and usually originates from limestone
Ordinary Portland Cement (OPC) Bosowa Cement is high quality portland cement that has met national standards, namely SNI 2049: 2015 and international standards namely ASTMC 150 / C150M-12 and European standards EN 197 -1 CEM I. Portland cement type I is a suitable type of cement for a wide variety of concrete applications where special requirements are not required.
USAGE:
Bosowa Ordinary Portland Cement (OPC) can be used for road building construction, bridges and buildings, in addition, several projects development in Indonesia also uses BSW Ordinary Portland Cement (OPC) composite such as Sultan Hasanuddin Airport, Bridge II of Samarinda City, Jayapura Underpass and so on.
Our Cement is a fine powder, obtained from the calcination at 1,450 C of a mix of limestone, clay, and iron ore. The product of the calcination process is clinker the main ingredient of cement that is finely ground with gypsum and other chemical additives to produce cement.
We offers an array of blended cements which have a lower CO2 footprint resulting from their lower clinker content due to the addition of supplementary cementitious materials. The use of blended cements reinforces our strong dedication to sustainable practices and furthers our objective of offering an increasing range of more sustainable products.
We are credible manufacturer and supplier of cement and are currently looking to build new relationships with potential buyers. Our Company has successful experiences in GCC ( Oman, Qatar and Kuwait) by offering the best quality and reasonable prices for cement.
We are pleased to supply the best quality products with your required tonnage as follow:
OPC (Ordinary Portland Cement) Type I 42.5 (bulk)
Test Results of Chemical Properties available

Other variants of cement types available based on your need
cement, in general, adhesive substances of all kinds, but, in a narrower sense, the binding materials used in building and civil engineering construction. Cements of this kind are finely ground powders that, when mixed with water, set to a hard mass. Setting and hardening result from hydration, which is a chemical combination of the cement compounds with water that yields submicroscopic crystals or a gel-like material with a high surface area. Because of their hydrating properties, constructional cements, which will even set and harden under water, are often called hydraulic cements. The most important of these is portland cement.
Ordinary Portland Cement Clinker is the core component in producing cement which is formed by sintering limestone. In the manufacturing of Portland cement, clinker formed by sintering or fusing together without melting to the point of liquefaction, alumina-silicate materials such as clay and limestone during the cement kiln stage and happens as 3 millimeters (0.12 in) to 25 millimeters (0.98 in) in diameter,
Ordinary Portland Cement Clinker is then ground to a fine powder and used as the binder in many Cementous goods. Sometimes, a little gypsum is also added. If stored in dry conditions, Cement Clinker can be kept for several months without considerable loss of quality. Because of this fact, and because it can be easily handled by ordinary mineral handling apparatus, Cement Clinker is highly traded intercontinentally in large quantities. At their cement plants, cement manufacturers which purchase clinker usually grind it as an addition to their own clinker. Producers also tend to ship their clinker to grinding plants in zones where cement-making raw materials are not available.
Arij Global Trading LLC, one of the independent traders of different types of clinker, gray and white in the area, supplies tons and tons of clinker annually. Arijâ??s special performance has led us to strong partnerships with global cement manufacturers as well as end-users. The Arij Global Trading has aggressively expanded its sources for clinker as well as other related merchandises to offer the most competitive rates under both CFR and FOB terms.
