How to Steam-Cure GRC Components in Low-Temperature Environments? — A Technical Guide to Winter Construction Curing

Steam curing of GRC components in low-temperature environments requires special control of the heating rate, holding time, and cooling speed to prevent thermal stress damage. In its northern projects, Qinglong Group adopts a gradient curing regime: heating ≤15°C/h, holding at 60-70°C, cooling ≤20°C/h, with curing time extended by 20%-30% to ensure normal strength development.

Low-temperature curing poses major challenges. Raw materials are preheated to avoid the freezing point. Curing kilns are insulated to reduce heat loss. Through these measures, Qinglong Group maintains normal production in winter. Monitoring is strict to prevent sudden temperature changes.

Scientific curing guarantees quality. Low temperatures never lower standards, and performance always meets requirements. With extensive experience, Qinglong Group delivers reliable low-temperature curing.
