WELCOME TO UAB SIRAS
We place great emphasis on innovation, service and quality in all aspects of our work. UAB Siras is known for its leading status in the supply of innovative alternative raw materials and scrap metal for foundries and steelworks. We also specialize in the supply of useful fuel products such as coal anode waste, electrode scrap, foundry coke and coke fines, and turnip pellets. But our advantage is that we are reliable suppliers with a wide range of products that meet the highest quality standards, all at an affordable price and in the shortest possible time.
We are proud of our close partnerships with a number of steel mills in various Eastern European countries, including Romania, Moldova and other Central European countries. These connections allow us to maintain high quality and speed of delivery at the international level. In addition, our network of buyers in the Middle East and Asia further expands our global presence and allows us to ensure stability and reliability in all our transactions.
We strive to provide our customers with the best innovative solutions, high quality and efficiency in the supply of raw materials and fuel products. Our efforts are aimed at ensuring reliable cooperation.
OUR PRODUCTS
Granulated Slag (Ground Granulated Blast Furnace Slag, GGBFS)
Definition
Granulated slag is an inert, glassy, granulated material obtained by rapidly cooling molten blast furnace slag with water or steam. When finely ground, it exhibits cementitious properties and can partially replace Portland cement.
Applications
Cement industry:
Active mineral additive to cement, improving strength and durability.
Key component in Portland cement type **CEM III** according to **EN 197.
Concrete production:
Enhances long-term strength.
Improves frost resistance.
Reduces heat generation during hardening, making it ideal for massive structures.
Road construction**:
Provides higher load-bearing capacity.
Increases resistance to freeze-thaw cycles.
Other uses:
Serves as a substitute for natural sand in insulating and filling applications.
Steel / Metallurgical Slag
Definition
Metallurgical slag is a by-product of iron- and steelmaking processes. Its composition depends on the raw materials and processes, but typically contains calcium, silicon, aluminum, iron, manganese, and phosphorus compounds.
Types of Metallurgical Slag
Air-cooled slag – dense, stone-like material obtained by natural cooling.
Granulated slag – cooled rapidly with water, forming granules suitable for cement additives.
Expanded (foamed) and pelletized slag – lightweight, porous materials used in specific construction applications.
Applications
Road construction:
Used as crushed stone in asphalt mixes and road base layers due to high load and abrasion resistance.
Railway infrastructure:
Applied as ballast and subgrade material.
Cement and concrete production:
Granulated slags are ground and used as additives to reduce clinker content.
Agriculture and soil improvement:
Enhances soil structure and regulates pH.
Can supply calcium, magnesium, and other trace elements.
Sustainable development:
Reduces demand for natural aggregates.
Decreases CO₂ footprint of cement and concrete production.
✅ Key Difference:
Granulated slag (GGBFS) – specifically produced for use as a cement additive, highly valued for its reactivity and cementitious properties.
General metallurgical slags – broader category with diverse uses (construction, agriculture, aggregates), not always
reactive as cement.
