Low Cement Castable: High-Performance Refractory for Modern High-Temperature Industries

Low cement castable (LCC) is a high-quality monolithic refractory widely used for industrial high-temperature furnace linings. It features a low calcium aluminate cement content of only 3% to 8%. Adopting ultrafine powder technology and optimized particle gradation, it overcomes the common defects of traditional high-cement castables and serves as a top-choice refractory solution for high-temperature, corrosive and abrasive industrial environments.

The material's greatest strength is its dense and stable internal structure. Traditional castables with high cement content form numerous pores and weak hydration compounds after curing and firing, resulting in poor high-temperature stability. Low cement castable replaces most cement binders with reactive ultrafine particles that fill voids between aggregates, lowering porosity and increasing bulk density. This delivers superior mechanical strength, excellent volume stability, and strong resistance to high-temperature shrinkage and cracking.

Low cement castable performs exceptionally well under harsh working conditions. It features outstanding thermal shock resistance and resists peeling and cracking during frequent drastic temperature changes. It also offers excellent abrasion resistance and chemical stability against erosion from high-temperature flue gas, slag and industrial chemical media.

This castable boasts excellent construction performance. It requires less water and provides good fluidity and workability for vibration pouring and integral molding. It creates seamless monolithic linings that avoid the structural weaknesses of brickwork.
