By mixing Balchip MK and Toughlite 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, "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 mixed spraying of reinforcement fibers on slopes and other areas, a more permanent weed prevention 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. "Balchip MK" has a long fiber length and a rough texture, 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, because each fiber is long and thick, the adhesion area within the mortar becomes smaller.

• Reinforced earth wall

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, making transportation and mixing easy. ■ Excellent chemical resistance and rust-proof. 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 the toe 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 suppression polypropylene short fibers, Toughlight, are processed in 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 suppression 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!

Prevent cracks in slope construction! Safe! Easy! Shortened construction period!

NETIS Registration Number: CG-070010-A "Kuratec" is a vinyl fiber for reinforcing mortar on slopes. By adding "Kuratec," it is possible to cut the lathing work process depending on site conditions, which can shorten construction time and achieve cost reductions. Additionally, it has good adhesion to cement, making it less prone to cracking, and if cracks do occur, it suppresses their growth. Furthermore, the quality of the mortar improves, allowing for a reduction in the thickness of the spray application. For more details, please contact us or download the catalog to view.
