This article will combine the hot content of the past 10 days to provide you with a structured maintenance guide.
1. The importance of cast-in-place maintenance on the roof
Improper maintenance of cast-in-place concrete on the roof will lead to problems such as cracking and insufficient strength, seriously affecting the quality of the building. According to the hot discussion on the Internet, the core of maintenance is to maintain humidity and temperature to prevent water from evaporating too quickly.
2. Steps and methods of cast-in-place roof maintenance
The following are the most discussed maintenance steps on the Internet:
| steps | method | time |
|---|---|---|
| Initial maintenance | Cover with damp cloth or plastic film | Within 24 hours after pouring |
| mid-term maintenance | Sprinkle water regularly to keep it moist | 3-7 days |

| local dryness | Uneven watering | Use spray equipment to spread water evenly |
4. Maintenance skills that are hotly discussed on the Internet
Based on recent hot topics, the following techniques are highly recommended:
1.Use curing agent: Spraying curing agent can reduce water evaporation, suitable for high temperature weather.
2.Shading measures: During summer construction, build a sunshade net to avoid direct sunlight.
3.temperature control: Construction in winter needs to be covered with insulation materials to prevent freezing damage.
5. Maintenance time reference table
Curing times vary depending on concrete type and climatic conditions:
| concrete type | Normal temperature curing time | High temperature curing time |
|---|---|---|
| Ordinary concrete | 7 days | 10 days |
| high strength concrete | 14 days | 21 days |
6. Summary
The maintenance of cast-in-place concrete on the roof is a key link to ensure the quality of the project. Through reasonable maintenance steps, problem solving and application of techniques, problems such as cracking and insufficient strength can be effectively avoided.
