Product Introduction
Advanced Low Cement Refractory Castables CH-LCC Series
Superior High-Temperature Performance with Reduced Water Consumption
Enhanced Thermal Shock Resistance & Quick-Drying Explosion-Proof Technology
Hubei Zhongnai New Material Technology Co., Ltd.
Leading Manufacturer of Advanced Low Cement Refractory Castable Solutions
Revolutionary Low Cement Castable Technology
Our Advanced Low Cement Refractory Castables CH-LCC Series represent a breakthrough in modern refractory technology, engineered with significantly reduced calcium aluminate cement content compared to conventional castables. These innovative materials consume only 50-70% of the water required by ordinary castables (approximately 5-7%), resulting in exceptional bulk density, ultra-low porosity, and superior high-temperature performance. Available in three specialized grades - High Aluminum Low Cement (CH-LCC65), Mullite Low Cement (CH-LCC70), and Corundum Low Cement (CH-LCC85) - our castables can be formulated as quick-drying explosion-proof variants according to specific baking time requirements.

Superior Performance Advantages Over Conventional Castables
Dramatically Reduced Water Consumption
Only 5-7% water requirement compared to 10-15% for conventional castables, enabling higher density and reduced porosity
Enhanced High-Temperature Performance
Significantly improved high-temperature strength and slag resistance due to greatly reduced cement content
Superior Thermal Shock Resistance
Excellent thermal shock performance comparable to sintered refractory products with minimal thermal expansion
Elimination of Dehydration Stage
No obvious dehydration stage during firing process, preventing strength loss during medium-temperature ranges
Quick-Drying Explosion-Proof Capability
Can be formulated as rapid-drying explosion-proof castables for accelerated turnaround applications
Preserved Hydration Bonding
Fewer hydrated compounds prevent bond destruction during firing, maintaining structural integrity
