Which grouting material is better for winter construction?
Runda Grouting Material answers: Early-strength grouting material is more suitable for winter construction, as it achieves faster rise in strength.
What is the suitable temperature range? Can it be used at -5 to -10 degrees Celsius?
No issues with construction at temperatures ranging from -5 to -10 degrees Celsius. There's also a support grouting material that can set within two hours when applied during winter.
Actually, it's fine even below -20 degrees; to be conservative, within -10 degrees.
Can concrete anti-freezing agent be added?
There's absolutely no need to add concrete anti-freezing agents. Adding them will damage the material's inherent structure and performance, leading to a decrease in strength.
How many types of grouting materials are available for winter construction?
General, Reinforced, Super-fine, Ultra-early strength, Ultra-fluidity, Support Type
Generally used for winter construction, the support type and ultra-early strength type, i.e., CGM-4.
Will the water freeze before it solidifies?
The grouting material will not produce heat after hydration, so it will not freeze and can be used with confidence.
Construction and Maintenance Tips: 1. Prefer to perform construction on hot days. 2. Use warm water to mix during construction (20-30°C). 3. Implement heating measures, such as covering with cotton blankets, using iodine tungsten lamps, and applying open flame, etc.
Do well on the above three points, and even regular grouting material will work great.
