Toda Industries delivered a brief of Barchip for concrete reinforcement in the review of Barchip demonstration organized by Toda Industries and Hagihara Industries at Mega Warehouse project. In this article, Toda Industries is going to give you more details of features, specifications and applications of Barchip products for your building projects.
Features
Concrete reinforcing fibre of Barchip is made of 100% Polypropylene and developed by Hagihara Industries Inc. Concrete reinforced with Barchip has a better flexural strength and toughness compared to those reinforced with steel rods.
- Light weight and workability: Barchip weighs only 0.91g and is well-packed, providing an ease of handling and workability.
- Corrosion free: Unlike steel rods, Barchip has a high resistance against alkali, thus ensuring the long-term durability of the concrete.
- High bonding with concrete: Thanks to Hagihara’s unique technology in embossing and hydrophilic treatment, Barchip provides a high bonding strength and improves a flexural toughness.
- Safer and ecological handling: Barchip does not release dioxin and clorine when inflaming. Therefore, it is known as a environmental-friendly material.
Specifications and applications of Barchip
Currently, Hagihara Industries has developed 3 types of Barchip: Barchip MK, Barchip JK and Barchip PW Jr. Here are their features.
Barchip MK
Barchip MK is a concrete reinforcing fibre for ground supported slab. Barchip MK is used as a replacement of steel reinforcement.

Conclusion
Concrete reinforcing fibre of Barchip have been used worldwide in an effort to reduce construction cost and increase long-term durability of concrete. In Vietnam, however, they are hardly applied for civil construction due to lack of information of products and reliable providers.
Hence, Toda Industries will be supplying high-quality Barchip products, which helps not only save much time and manforce but also minimize cost of materials in the near future in cooporation with Hagihara Industries.
