Q: How long does your cement road repair material last?

The working principle of the cement road repair material is that it carries special cement with high polymer materials, which penetrate and physically bond to the original road surface, ensuring a firm bond between the repair layer and the original foundation, forming an integrated whole. The strength of the repair layer is 1-3 times greater than the base strength, thereby guaranteeing the long-term use of the repaired road. Note: Road traffic conditions vary, but under normal traffic volumes, the lifespan can reach over 8 years. A parking garage in Chengdu, which used our product for repair due to surface sanding in 2013, has remained flawless and relatively bright for over a decade.

Q: How do you ensure that your materials don't peel or crack, and that they are drivable in 2 hours?

Answer: Sichuan Fan Chen's road repair material contains over 2% of polymer (re-dispersible latex powder), ensuring the material's physical bonding strength. It includes penetrating components that allow the repair paste to penetrate the internal voids of the base, guaranteeing the repair layer does not delaminate. The internal mixture features shrinkage compensation ingredients and anti-cracking fibers, reducing the shrinkage and cracking of the repair material to a minimum. The material uses special cement and lithium carbonate catalyst, resulting in a setting time from initial to final of only about 15 minutes, with a compressive strength of over C30 after 2 hours, ensuring that the repair material is safe for pedestrian traffic within 30 minutes and open to traffic within 2 hours.

Q: Why is your cement road repair material priced at 2,600 yuan per ton?

Answer: The material cost for Sichuan Fan Chen cement road repair material is too high in a 20-degree environment, ensuring 2-hour traffic restoration. The cost of cement, a special type, is over 1300 yuan per ton, polymer powder content is above 2% with a cost of about 600 yuan, the catalyst lithium carbonate content is at 0.1% with a cost of around 650 yuan, and the material cost for one ton of repair material is approximately 2100 yuan plus additional costs such as packaging, labor, electricity, etc., totaling about 200 yuan, plus a company profit of 10%.

Q: Are there other product specifications available?

Response: Available in various repair types and usage conditions are: ZTZ-101 (thin-layer lying flat repair material), ZTZ-102 (thick-layer cast material), and ZTZ-103 (oblique surface quick scraping material).

Q: What are the advantages of the product's H compression?

Our materials undergo rigorous testing by professional technicians, evaluating their compressive strength at both standard laboratory temperatures and outdoor operating temperatures. The actual test data from February 26, 2023, are as follows: Laboratory temperature 20°C: 1 hour - 18.6 MPa, 2 hours - 33.5 MPa; Outdoor temperature 11.3°C: 1 hour - 13.6 MPa, 2 hours - 26.5 MPa.

Q: Can you give a full introduction to the h flexural strength?

Our materials undergo professional testing by qualified personnel, ensuring they meet both standard laboratory and outdoor usage temperatures, and testing their 2-hour and 24-hour flexural strength. The actual test data from February 26, 2023, are as follows: Laboratory temperature of 20°C: 2-hour strength of 6.6 MPa, 24-hour strength of 12.5 MPa; Outdoor temperature of 11.3°C: 2-hour strength of 5.6 MPa, 24-hour strength of 13.5 MPa.

Q: Are there any other products with initial gel time?

Our materials undergo professional testing by technicians, measuring initial and final setting times at standard experimental temperatures and outdoor usage temperatures. The actual test data from February 26, 2023, are as follows: Laboratory temperature of 20°C: initial setting time of 18 minutes, final setting time of 36 minutes; outdoor temperature: initial setting time of 31 minutes, final setting time of 48 minutes.

Q: Do you ship out of province?

We can ship to provinces outside of Sichuan; our company is based in Chengdu, making it convenient to deliver nationwide.

Are you a manufacturer?

We are a professional manufacturing factory, located at Building A3-4, Xinhe Industrial Park, Pengzhou, Chengdu, Sichuan. Our factory holds certifications for environmental assessment, safety assessment, and ISO, so please feel confident in making your purchase.

Q: Can it be customized?

Answer: Customizable, but a minimum order of 2 tons is required for customization!

Q: Are there any in stock?

Our factory directly supplies stock items, with a regular inventory of road patching materials around 100 units. Each production batch is approximately 85 tons (for special cement, the incoming quantity is 34 tons, which can produce around 85 tons of road patching materials).
