NASAKI TERRAZZO TILES’ RIGOROUS STANDARD PRODUCTION PROCESS: CREATING SUSTAINABLE BEAUTY FROM GREEN MATERIALS

In modern architectural trends, Terrazzo tiles are making a spectacular comeback, becoming the preferred cladding and flooring material for industry professionals in numerous projects. Not only bringing unique artistic aesthetic value, Nasaki Terrazzo tiles also assert their superiority through a production process that adheres to strict technical standards. In particular, the application of a circular economy model, utilizing industrial by-products, has helped Nasaki Terrazzo become a symbol of "green materials"—eco-friendly and durable over time.

1. Green Raw Materials: An Innovative Solution for Utilizing By-products

The core difference creating the essential value of Nasaki Terrazzo lies in the input material selection stage. Instead of aggressively exploiting new natural resources, the production process at the Nasaki factory prioritizes the reuse of by-products from the natural stone mining and processing industry.

• Utilizing stone chips and stone powder: During the process of cutting natural stone blocks (such as Marble, Granite, Limestone), a huge amount of stone chips and powder is discarded, putting heavy pressure on the environment. Nasaki has pioneered collecting, classifying, and processing these by-products to transform them into the main aggregates that make up the tiles.

• Diversifying decorative aggregates: Besides stone powder and chips, crushed marble fragments and natural pebbles are skillfully blended with high-strength cement to create beautiful terrazzo slabs.

• Sustainable development: Utilizing recycled materials not only thoroughly solves the industrial waste problem and limits new mining but also minimizes carbon emissions compared to traditional ceramic tile production.

2. Nasaki Terrazzo Production Process: Precision in Every Stage 

To transform raw aggregates into sophisticated Terrazzo tiles, the Nasaki factory applies a closed-loop technology line with 4 extremely strict quality control stages:

• Step 1: Golden Ratio Mixing: Materials including cement, stone chips, stone powder, and decorative aggregates are precisely quantified. The mixing ratio is the "heart" that determines the load-bearing strength and uniform distribution of stone particles on the surface. The mixture undergoes dry mixing, then wet mixing so that the cement completely coats the aggregates, creating the strongest chemical bond.

• Step 2: High-Pressure Hydraulic Pressing: This is the key stage determining the mechanical durability of the tiles. The mortar mixture is poured into a steel mold with absolute mechanical precision. A hydraulic press with immense intensity (up to 500 tons/product) compresses the entire material block. This massive force squeezes out excess water and air inside, eliminating voids and creating a dense block with superior waterproofing capabilities.

• Step 3: Natural Curing: Unlike fired materials that consume combustion energy, Nasaki Terrazzo tiles after pressing are moved to a curing area under standard temperature and humidity conditions. The hydration process of cement takes place naturally for 21 to 28 days. This ensures the tiles achieve maximum compressive and flexural strength before entering the surface finishing stage.

• Step 4: Grinding, Polishing, and Protective Coating: The raw surface undergoes a multi-level grinding line (from coarse diamond discs to fine polishing discs) to reveal the exquisite beauty of the stone particles. The grinding process uses a closed-loop water circulation system, with no discharge into the environment. Finally, the surface is coated with a specialized penetrating sealer to provide antibacterial, waterproof, and stain-resistant properties while maintaining natural gloss for decades.

3. Superior Technical Characteristics from standard processes 

Thanks to the perfect combination of recycled materials and advanced hydraulic pressing technology, Nasaki Terrazzo tiles possess superior physical and mechanical properties, meeting the standards of large-scale projects:

• Maximum Load-Bearing Durability: With high compressive and flexural strength, the product withstands continuous loads and traffic density. Nasaki Terrazzo tiles completely eliminate the risk of cracking or subsidence, making them an ideal solution for hotel lobbies, squares, or commercial centers.

• Challenging the Limits of Time: Nasaki Terrazzo maintains a stable structure throughout the project's life cycle. After 10-15 years of use, if the gloss decreases due to friction, a simple polishing process will restore 100% of the original beauty without needing replacement.

• Optimizing Long-term Costs: The product brings sustainable financial benefits thanks to highly competitive initial material costs compared to natural stone, while minimizing maintenance, upkeep, and cleaning labor costs (OPEX).

4. Summary

Adhering to a rigorous production process is not only a commitment to quality but also a clear testament to Nasaki Vietnam's vision for sustainable development. The birth of Nasaki Terrazzo tiles has broken the prejudice against resource-consuming construction materials. By effectively utilizing stone chips and powder and applying modern non-fired technology, Nasaki Terrazzo provides a comprehensive tiling solution: creating luxurious, artistic living spaces while protecting the ecosystem and maintaining beauty despite the harshness of time.
