By mixing Balchip MK and Toughlight RG for mortar spraying, the crack occurrence rate in mortar structures is further reduced!

The mortar reinforcement fiber mixed spraying proposed by K.F. involves mixing polypropylene fibers for mortar reinforcement, "Varchip MK," with crack suppression polypropylene short fibers, Toughlight RG, and spraying them. This method reduces the crack occurrence rate in mortar structures, thereby enhancing durability and lowering lifecycle costs. By performing mixed spraying of reinforcement fibers on slopes and other areas, a more lasting weed suppression effect can be expected. 【Why is the crack occurrence rate reduced?】 Reinforcement fibers have various characteristics depending on their type, each with its own advantages and disadvantages. "Varchip MK" has a longer fiber length and a rough surface, allowing the mortar to cling to each fiber, making it difficult to pull out and providing crack prevention effects (cross-linking effect). Additionally, as the bending toughness increases, it is possible to omit the wire mesh and reduce the spraying thickness. However, since each fiber is long and thick, the adhesion area within the mortar decreases.

It is a polypropylene fiber for mortar reinforcement that excels in workability and chemical resistance.

For crack suppression in slope construction! NETIS registration number: KT-100021-VE. ■ Lightweight and excellent workability. With a density of 0.91g/cm3, it is light and easy to transport and mix. ■ Excellent chemical resistance and rust-free. It has superior alkali resistance and durability. ■ Adhesion to concrete. Embossed processing and hydrophilic treatment improve adhesion and enhance bending toughness. ■ Environmentally friendly. It does not produce dioxins (chlorine gas) when burned. 【Proposal: Weed prevention using reinforced fiber mixed spraying】 At K-F, we propose "weed prevention work using mortar reinforced fiber mixed spraying." Mortar reinforced fiber mixed spraying involves mixing polypropylene fibers for mortar reinforcement, "Balchip MK," with crack suppression polypropylene short fibers, Toughlight RG, and spraying them to further reduce the crack occurrence rate in mortar structures, thereby enhancing durability and reducing lifecycle costs. By performing reinforced fiber mixed spraying on slopes, such as at the base of the slope, more lasting weed prevention effects can be expected.

For suppressing shrinkage cracks in sprayed mortar! Safe material made of polypropylene! Crack-suppressing short fibers that can be mixed with a mixer.

Crack-inhibiting polypropylene short fibers, Toughlight, are processed into bundles, making them less likely to scatter and less likely to pierce the skin. Furthermore, since polypropylene is the material used, no toxic gases are generated during combustion, making it a highly safe crack-inhibiting short fiber. 【Incorporation Effects】 ● Reduces scattering and collapse during spraying ● Reduces shrinkage cracks caused by temperature changes and drying during the curing period 【Excellent Workability】 ● Easily mixed with a conventional mixer ● Generates few fiber balls and has high degradability ● The flow value remains unchanged with the incorporation of Toughlight, maintaining fluidity ● During spraying operations, fibers do not pierce like needles due to rebound There are many other features as well!

In construction work, it is important not only to focus on the building itself but also to create a safe environment for construction vehicles and workers to move around. The Hyper CLT plywood is a lightweight wooden board that utilizes CLT. It can be used as temporary materials to support temporary roads, material delivery routes, heavy machinery work yards, material storage areas, and worker pathways, rather than as structural materials for buildings. The 5×10 board weighs approximately 230 kg, making it relatively lightweight and easy to install, remove, or relocate depending on site conditions. This allows for the boards to be moved in accordance with the progress of the construction, making it easier to effectively utilize limited space. Additionally, the natural texture of the wood blends well with construction sites in residential areas and around public facilities, contributing to considerations for metal noise and summer heat reflection. The Hyper CLT plywood is a registered technology under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS system, designated as "TH-250021-A." It can be incorporated into highly public construction projects and exterior and earthworks, promoting the use of new technologies and environmental considerations. Wooden plywood, NETIS, civil engineering, CLT, lightweight wooden boards. A new option for temporary materials using wood is available for construction sites.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or variations in dimensions, can be molded at the same time in a single molding process. This allows for the verification of multiple types in a short period.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs often change the base material around the crack due to heat, leading to residual stress and deformation, which constantly carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
