"Glassless Sand" is a weed control method that involves spreading a pavement material made by mixing blast furnace water-quenched slag as aggregate with cement and admixtures within a formwork, and then compacting it to a specified thickness. By utilizing the latent hydraulic properties of blast furnace slag, it can sustain weed control effects in a long-term and stable manner, ensuring a good landscape and visibility, as well as preventing the occurrence of pests, thereby maintaining a comfortable living environment. Additionally, by allowing rainwater to permeate through the surface of the weed control work and return to the ground, it contributes to the prevention of global warming and the reduction of environmental impact. [Features] ■ Contributes to the sanitary environment for residents living in the area through weed control work ■ Environmentally oriented with a rich variety of color options, considering landscape aesthetics ■ Contributes to the prevention of global warming and the reduction of environmental impact *For more details, please refer to the PDF materials or feel free to contact us.

By using blast furnace crushed slag as the main aggregate, we have eliminated the peeling and flaking that were seen in the initial stages of conventional earth pavements. The durability is also excellent due to the slag's "latent hydraulicity" (a characteristic where strength increases over time due to hydration reactions). It has a natural color and texture similar to soil, without the artificial impression often seen in asphalt or resin-based materials. It also excels in functions such as permeability, water retention, and slip resistance. 【Features】 ■ Main composition of blast furnace crushed slag mixed with sandy soil ■ Resistant to water overflow on the surface, accommodating heavy rainfall of 30mm/h ■ Mitigates the heat island effect through evaporation from the surface ■ Provides moisture to trees and flowers through evaporation, promoting growth ■ Universal design that is easy for anyone to walk on ■ Extended lifespan compared to conventional paving materials ■ Reduces the extraction of natural materials by using artificial aggregates (recycled materials) *For more details, please refer to the PDF document or feel free to contact us.

"Eco-Cool Sand" is an environmentally friendly paving material that reuses waste melting slag. It uses "melted slag," which is processed from household "living waste," and "blast furnace crushed slag," a byproduct of steelmaking, as aggregates. It excels in permeability and water retention, and mitigates the heat island effect through evaporation from the surface. In addition to not creating steps like blocks, it provides a non-slip and soft walking sensation, reducing the burden on the legs and back, thus achieving a user-friendly pavement. 【Features】 ■ Excellent permeability and water retention, capable of handling rainfall of 30mm per hour ■ Mitigates the heat island effect through evaporation from the surface ■ Designated material under the Green Purchasing Law, with a recycling rate of over 80% ■ Flat and compliant with "Universal Design" standards ■ Exhibits excellent weed prevention and durability, harmonizing with the surrounding landscape *For more details, please refer to the PDF materials or feel free to contact us.
