What is the use of ceramsite sand?
As a lightweight porous material, ceramsite sand has been widely used in construction, environmental protection, agriculture and other fields in recent years. The following is a compilation of hot topics and hot content about ceramsite sand on the Internet in the past 10 days, showing its uses, advantages and market trends through structured data.
1. Main uses of ceramsite sand
| Application areas | Specific use | Advantages |
|---|---|---|
| construction industry | Lightweight concrete, sound and thermal insulation materials, green roofs | Light weight, good thermal insulation and strong shock resistance |
| Environmental protection project | Sewage treatment, exhaust gas filtration, soil remediation | Strong adsorption and high chemical stability |
| Agriculture and Horticulture | Soilless cultivation, soil improvement, flower planting | Breathable, water-retaining, preventing hardening |
| Industrial field | Petroleum proppant, refractory materials | High temperature resistance and high compressive strength |
2. Recent hot topics
1.Demand for building energy conservation drives ceramsite sand market growth: As green building standards improve, the application of ceramsite sand in wall insulation has become a hot topic, and related searches have increased by 15% month-on-month.
2.Environmental protection policies drive demand for sewage treatment: Many places have introduced policies to upgrade sewage treatment plants. Ceramic sand has attracted much attention as a filler for biological filters. The number of discussions on an environmental protection forum exceeded 1,000 in a single week.
3.The rise of urban agriculture: Balcony planting enthusiasts recommend ceramsite sand as an alternative to traditional soil. Data from an e-commerce platform shows that its sales increased by 40% year-on-year.
3. Comparison of physical properties of ceramsite sand
| Features | Ceramic sand | Ordinary sand and gravel |
|---|---|---|
| Density(g/cm³) | 0.6-1.2 | 2.5-2.7 |
| Porosity (%) | 50-70 | <10 |
| Water absorption (%) | 8-15 | 1-3 |
4. Precautions when purchasing
1.Select particle size according to application: 3-5mm is recommended for gardening, and 5-20mm is required for construction aggregate.
2.Check chemical stability: The pH value of high-quality products should be neutral (6.5-7.5) to avoid excessive heavy metals.
3.Pay attention to origin information: The quality of industrial clusters in Shandong, Jiangsu and other places is relatively stable, and the products of newly put into production in Hebei recently have outstanding cost performance.
5. Future development trends
1. The research and development of modified ceramsite sand is accelerated. A team from a university announced a new nano-coating technology that can increase the pollutant adsorption efficiency by 30%.
2. The expansion of the international market, infrastructure construction in Southeast Asia has driven the growth of export orders, and the monthly export volume of one company exceeded 2,000 tons.
3. Recycled ceramsite sand technology has attracted attention. The cost of environmentally friendly products produced using construction waste has been reduced by 20%, which is in line with the policy guidance of circular economy.
To sum up, with its unique physical properties, ceramsite sand is expanding its application from traditional building materials to many fields. With technological progress and policy promotion, the market potential will continue to be released in the future.
