Refractory Cement Concrete (1000°C)

Refractory Cement Concrete is a specialized thermal insulation material crafted from a blend of alumina and silica-based components. Distinguished from more robust structural castables and bricks, this lighter-duty version serves a specific purpose as a repair and bonding material. Packing in convenient 25 kg bags, it is designed for various applications in high-temperature environments, indicating its focused functionality rather than serving as a primary lining solution. Its unique formulation allows seamless integration into diverse industrial projects requiring dependable thermal management.

The engineering characteristics of Refractory Cement Concrete stem from its alumina and silica makeup, which confer exceptional thermal stability and mechanical strength. With a compressive strength of over 15 MPa, this material is engineered to endure significant structural loads while maintaining durability under thermal stress conditions. The carefully selected composition not only enhances resistance to high temperatures, rated continuously at up to 1000°C, but also improves the material's ability to withstand thermal cycling without compromising integrity, making it especially suitable for furnace backup and mold-making tasks.

In service, the performance metrics of Refractory Cement Concrete demonstrate its reliability under demanding conditions. With a density of 1,650 kg/m³, it minimizes the risks of deformation and ensures effective heat regulation, thereby safeguarding essential equipment from thermal degradation. The thermal conductivity rating of 0.60 W/m·K at 250°C indicates its efficiency in maintaining operational temperatures while reducing heat loss, ultimately enhancing energy efficiency and operational safety for the user.

Available primarily in 25 kg bags, Refractory Cement Concrete can be conveniently sourced in various packaging options tailored to the buyer's needs, including bulk bags or pallets. Prospective customers should confirm specific ordering requirements, including quantity and preferred packaging format, to ensure optimal supply. Zenco Systems Ltd is positioned to meet the demand for this essential material across Nairobi and the broader East African region.

Refractory cement concrete sits at the lighter-duty end of Zenco's refractory range — rated to 1000°C with a ≥15 MPa compressive strength and 1,650 kg/m³ density, each figure notably lower than our structural castable and brick products, which reflects its role as a backup, repair, and bonding material rather than a primary furnace lining. Buyers specify it for furnace linings in steel production, boiler shell lagging in power plants, kiln backups in ceramics production, high-temperature mortar for construction joints, heat shields in industrial ovens, casting applications in metalworks, thermal insulation for pipelines, backup material for refractory bricks, sealants for high-temperature equipment joints, reinforcing layers in industrial heating systems, mould making for cement products, surface bonding in refractory setups, and repair material for damaged linings — spanning steel, cement manufacturing, power generation, ceramics, glass production, petrochemical, and metal casting industries. It's also known by generic names — refractory mortar, castable cement, heat-resistant concrete, or high-temperature cement — describing this general class of lighter-duty refractory binder. It's supplied in 25kg bags, packed on pallets, as bulk bags for large orders, or in cardboard boxes with inner liners for smaller shipments, with shrink-wrapped bundles available for transport. Mix at a water-to-cement ratio of 0.1 to 0.25, tested to ASTM C92 — straying outside that ratio is the most common cause of poor bond strength when used as a backup or repair material. Because its ratings sit below our dedicated castable and brick lines, don't specify it as a primary hot-face lining in high-mechanical-load zones — it's built for backup, bonding, and repair duty.
