In the field of construction and decoration, washed stone rice is a common decorative material and is widely used in the construction of walls, floors and other parts. Choosing the right cement is crucial to the construction effect of stone washing rice. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the selection of cement in the construction of stone washing rice, and provide structured data for reference.
1. Requirements for cement in stone washing rice construction
Stone-washed rice construction usually requires cement with the following properties:
1.Strong adhesion: Can firmly bond stone rice particles to avoid falling off.
2.Good weather resistance: Resistant to climate change and not prone to cracking or powdering.
3.color matching: The color of cement should be coordinated with the color of stone rice to avoid affecting the final effect.
4.Good construction performance: Easy to stir and apply, improve construction efficiency.
2. Types of cement suitable for stone washing rice construction
According to popular discussions and industry experience in the past 10 days, the following cement types are suitable for stone washing rice construction:
| cement type | Features | Applicable scenarios |
|---|---|---|
| Ordinary Portland cement | Strong adhesion and economical price | General stone washing rice construction |
| white portland cement | White color and high aesthetics | Light colored stone or art deco |
| polymer modified cement | Good weather resistance and strong crack resistance | Outdoor or demanding projects |
| Fast hardening sulphoaluminate cement | Fast condensation, high early strength | Projects with tight deadlines |
3. Key indicators for cement selection
When choosing cement, you need to focus on the following indicators:
| indicator | Standard value | Detection method |
|---|---|---|
| Initial setting time | ≥45 minutes | GB/T1346 |
| Final setting time | ≤10 hours | GB/T1346 |
| 3 days compressive strength | ≥10MPa | GB/T17671 |
| 28-day compressive strength | ≥32.5MPa | GB/T17671 |
4. Construction precautions
1.Cement to stone rice ratio: It is generally recommended that cement:stone and rice=1:2.5~1:3 (weight ratio).
2.Stirring requirements: Stir thoroughly to avoid dry powder or agglomeration.
3.construction environment: The temperature should be between 5-35℃, and construction should be avoided on rainy days or strong windy days.
4.Maintenance requirements: It needs to be kept moist and cured for at least 7 days after construction.
5. Recommendations of popular cement brands in the market
According to recent market research and consumer feedback, the following brands of cement perform well in stone washing rice construction:
| brand | Product series | Features |
|---|---|---|
| Conch cement | P·O42.5 | Stable strength and high cost performance |
| Huaxin Cement | White cement series | High whiteness and good decorative effect |
| Jidong Cement | polymer modified cement | Outstanding crack resistance |
| BBMG Cement | Special cement series | Suitable for special environments |
6. Frequently Asked Questions
1.Question: Can ordinary cement be used for stone washing rice?
Answer: Yes, but pay attention to the color matching. Dark stone rice is more suitable for ordinary cement.
2.Question: What should I do if grains fall off after stone washing rice is constructed?
Answer: It may be due to insufficient cement usage or improper maintenance. It is recommended to increase the proportion of cement and strengthen maintenance.
3.Q: Will white cement turn yellow?
Answer: High-quality white cement has good anti-yellowing properties, but may become slightly discolored after long-term exposure to the sun.
7. Conclusion
Choosing appropriate high-quality cement is the key to ensuring the effectiveness of stone washing rice construction. It is recommended to select the most suitable cement type and brand based on specific project requirements, budget and design effects. At the same time, only by strictly controlling the construction technology and maintenance procedures can we achieve the ideal decorative effect.
