Heat-conducting moisture-retaining slag pavement material "Heat Through Sand"

Heat-conducting moisture-retaining slag pavement material "Heat Through Sand"

Releases heat and lowers surface temperature! It is an environmentally friendly pedestrian pavement material.

"Heat Through Sand" is a pedestrian pavement that combines high-permeability and water-retaining blast furnace crushed slag with high thermal conductivity aggregates (such as silica) in an optimal mix, adding cement, admixtures, and inorganic pigments, resulting in an environmentally friendly pavement that possesses both permeability and water retention functions as well as thermal diffusion capabilities. Since blast furnace crushed slag is a porous aggregate, it allows for "permeability across the entire surface," not just through the gaps between aggregates like conventional permeable pavements. This characteristic makes it less prone to clogging from debris, allowing the permeability and water retention functions to last for a long time. 【Features】 - Rainwater is stored in the fine porous voids of the blast furnace crushed slag from the surface. - Rainwater that permeates into the base is drawn up through capillary action, sustaining the evaporation effect over a long period. - Incorporation of high thermal conductivity aggregates such as silica. → In summer, heat stored in the surface layer is conducted and diffused to the base, reducing surface temperature. → In winter, geothermal heat from the base and subgrade is conducted and diffused to the surface, helping to suppress surface freezing. For more details, please contact us or download the catalog.

Permeable soil-based slag paving material "Eternal Sand"

Permeable soil-based slag paving material "Eternal Sand"

Earth-based slag pavement that solves the weaknesses of earth-based pavement.

By using blast furnace crushed slag as the main aggregate, we have eliminated the peeling and flaking that were observed in the initial stages of conventional soil pavements. The "latent hydraulicity" of the slag (a characteristic that increases strength over time due to hydration reactions) also contributes to its excellent durability. 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 ingredient is blast furnace crushed slag mixed with sandy soil ■ Resistant to overflowing water 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.

The reason why colored sand is strong against "freeze-thaw" cycles.

The reason why colored sand is strong against "freeze-thaw" cycles.

Introducing technical information about permeable blast furnace slag pavement "Color Sand"!

This document explains the reasons why "permeable and water-retaining pavement materials (color sand)" are strong against "freeze-thaw" cycles. Color sand is a pedestrian pavement material that possesses permeable and water-retaining functions while being sufficiently resistant to the repeated effects of freeze-thaw cycles in winter, making it "strong against frost damage." Among our pavement composition, the "filter layer" made from high furnace slag pavement, which is the aggregate of this pavement material, has a significant effect in suppressing "frost heave" when used alone. Furthermore, in freeze-thaw tests conducted at the Central Testing Laboratory of the Building Materials Testing Center, no cracking or destruction occurred even after completing 200 cycles. 【Excellent Features of the Aggregate (High Furnace Slag)】 ■ Porous Structure - Numerous fine voids relieve pressure caused by volume expansion during freezing. ■ Potential Hydraulicity - The main components of water-quenched slag (silica, alumina, lime, magnesia) solidify over time due to repeated water infiltration. ◎ Sufficiently resistant to the repeated effects of freeze-thaw cycles. *For more details, please refer to the PDF materials or external link pages, or feel free to contact us.
