What to use for broken concrete: Analysis of hot topics and hot content on the Internet in the past 10 days
With the rapid development of the construction industry, the recycling of broken concrete has become a hot topic recently. This article will extract key information from the hot content on the Internet in the past 10 days, analyze application scenarios, technology trends and market dynamics of broken concrete, and present it in structured data.
1. Common application scenarios of broken concrete
| Apply scenario | Proportion | Popular areas |
|---|---|---|
| Road base filling | 35% | Guangdong, Jiangsu, Zhejiang |
| Recycled aggregate production | 28% | Beijing, Shanghai |
| Construction waste backfill | 22% | Sichuan, Hubei |
| garden landscaping | 15% | Fujian, Yunnan |
2. Technology trend analysis
In the past 10 days, discussions on broken concrete treatment technology have mainly focused on the following directions:
1.Intelligent sorting technology: Using AI to identify steel impurities in concrete blocks, the sorting efficiency increases by 40%.
2.Micronization regeneration technology: Break concrete down to the micron level and use it for 3D printing building materials.
3.Carbonization curing process: Using CO₂ to maintain recycled concrete, the strength is increased by 25%.
| Technical name | search index | Patent growth |
|---|---|---|
| Intelligent sorting | 8,542 | +17% |
| Micronization regeneration | 6,237 | +32% |
| Carbonization maintenance | 5,689 | +21% |
3. Market dynamics and policy trends
1.price fluctuations: The price of recycled aggregates has increased by 12% this month, and demand exceeds supply in some areas.
2.policy support: The Ministry of Housing and Urban-Rural Development’s new regulations require that the construction waste reuse rate must reach 60% by 2025.
3.Enterprise layout: Leading companies such as Conch Cement have recently added crushed concrete processing production lines.
| Company name | Investment amount | Estimated production capacity |
|---|---|---|
| Conch cement | 320 million | 500,000 tons/year |
| Huaxin Cement | 280 million | 450,000 tons/year |
| BBMG Group | 150 million | 300,000 tons/year |
4. Comparison of environmental protection benefit data
Compared with traditional treatment methods, the reuse of broken concrete shows significant environmental advantages:
| indicator | traditional landfill | Recycling |
|---|---|---|
| Carbon emissions | 1.8 tons/ton | 0.6 tons/ton |
| land occupation | 2.5m³/ton | 0.3m³/ton |
| water consumption | 1.2 tons/ton | 0.4 tons/ton |
5. Industry Pain Points and Solutions
1.High sorting costs: Some companies use a combination of magnetic separation + manual sorting to reduce costs.
2.Unstable strength: Adding 10-15% silica fume can improve the strength of recycled concrete.
3.Low market acceptance: "Recycled building materials demonstration projects" have been carried out in many places to enhance awareness.
Conclusion
The recycling of broken concrete is changing from a simple environmental protection requirement to a technological innovation field with economic value. With increased policy support and technological breakthroughs, the market size is expected to maintain an average annual growth rate of more than 20% in the next three years. Construction companies should focus on cutting-edge technologies such as intelligent sorting and carbonization maintenance, and lay out the recycled building materials track in advance.
