1, after concrete pouring, it should be covered and watered within 12 hours. First plastic, then sacks, then watering. 12 hour is the theoretical time and room temperature, and someone covers it in 6 hours.

2, do not water in winter, because the plastic film can keep moisture and make it less volatile, but also for antifreeze consideration. Theoretically, when the daily average temperature is lower than 5℃, watering and maintenance are not allowed, and it is appropriate to cover the insulation with plastic film or sacks and straw bags.

3. In summer, the temperature is high, the humidity is low, and it dries quickly. The water and soil conservation method is the first choice for sustainable maintenance. One or two days before concrete pouring, the concrete should be kept fully wet. For large-scale flat slab projects, curing with curing liquid is more practical and convenient. To put it bluntly, it is water storage. Thermal insulation and heat storage in winter.

To add a question, it is to keep warm in winter and moisturize in summer.
