Theoyunbei dark grey paving stone tiles
Product Introduction
Theoyunbei dark grey paving stone tiles are a natural imitation dark grey granite paving material synthesized from natural basalt aggregate and high-strength cement substrate. They are characterized by "industrial durability+natural rough aesthetics" and are suitable for scenes that require high strength and visual unity, such as municipal roads, commercial squares, and industrial landscapes.
Product advantages
1. Ultimate compressive and wear-resistant performance
The compressive strength is ≥ 60MPa (far exceeding the 30MPa of C40 concrete bricks), and it can withstand frequent crushing by heavy vehicles such as fire trucks and freight trucks.
Mohs hardness level 7 (close to natural basalt), abrasion resistance test (ASTM C418) shows a wear loss of<0.5mm over 50 years. Compared to natural dark granite, although natural dark granite has higher compressive strength, it is brittle and prone to edge cracking. The Theoyunbei dark grey giving stone tiles product would not have this situation
2. Theoyunbei dark grey giving stone tiles have more stable colors and stronger anti fouling technology
Inorganic mineral staining, does not fade after 1000 hours of ultraviolet irradiation.
Oil repellent nano coating extends oil penetration time to 2 hours (only 10 minutes for natural stone), improving cleaning efficiency by 80%. Ordinary dyed concrete bricks: Fading patches appear after 1-2 years (especially in high salt coastal areas). Natural dark gray limestone: easily corroded by acid rain to form white spots. This is the conclusion drawn by our company's professional laboratory researchers after years of investigation and research. In order to avoid this drawback, we have developed this product.
3. Construction economy and efficiency
Modular design (standard size 600 × 400mm), capable of mechanical paving, with an efficiency of 200 ㎡/person/day (natural stone manual paving only 50 ㎡/person/day).
Base compatibility: It can be directly laid on asphalt base, saving 30% of base material costs.
4. Eco friendly features, Theoyunbei dark grey giving stone tiles are more environmentally friendly
The aggregate contains 40% recycled building materials (crushed concrete particles) and has passed SGS environmental certification.
Surface microporous structure (porosity 8% -10%), with both permeability (permeability 0.8cm/s) and slip resistance (BPN value 75, higher than European standard 65).
