Reasons 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 during winter, making it "strong against frost damage." Among our pavement composition, the "filter layer" made from high furnace slag pavement, when used alone, has a significant effect in suppressing "frost heave phenomena." 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 release pressure caused by volume expansion during freezing. ■ Potential Hydraulic Properties - The main components of water-cooled slag (silica, alumina, lime, magnesia) solidify over time due to repeated water penetration. ◎ 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.

The technical basis of "permeable blast furnace slag pavement" that balances permeability and water retention.

Introducing technical information about permeable and water-retaining blast furnace slag pavement "Color Sand"!

We will explain the technical basis of the "Permeable and Water-retaining Blast Furnace Slag Pavement (Color Sand)" that achieves both permeability and water retention. All of our paving materials use "water-quenched blast furnace slag" as the main aggregate. The aggregate itself has a fine porous structure, allowing it to provide both permeability and water retention. While typical permeable paving materials allow water to pass through at "points," our paving materials enable permeability across "surfaces" due to the nature of the aggregate itself, resulting in less clogging and maintaining permeability performance over a long period. Additionally, by cleaning with high-pressure washers, the permeability can be restored to about 80%. Further explanations regarding "permeability performance" and "water retention performance" can be found through external links. 【Introduction to Technical Information】 ■ Reasons for achieving both permeability and water retention ■ Permeability performance ■ Water retention performance ■ Our product lineup *For more details, please refer to the PDF materials or external link pages, or feel free to contact us.

About the characteristics and benefits of blast furnace crushed slag used in colored sand.

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

This document explains the characteristics and benefits of the blast furnace crushed slag used in "permeable blast furnace slag pavement (color sand)." The "blast furnace crushed slag" used as aggregate in our paving materials is a byproduct generated simultaneously when producing pig iron from a blast furnace at major steel manufacturers. It can be easily separated as it floats on top of the molten pig iron. In addition to contributing to environmental load reduction, it has characteristics such as excellent gradation balance due to its uniform particle size. Further explanations on topics such as "What is steel slag?" and "Characteristics and general uses of blast furnace slag" can be found through external links. 【Technical Information Introduction】 ■ What is "steel slag"? ■ Characteristics and general uses of "blast furnace slag" ■ Reasons for adopting "blast furnace crushed slag" - Environmental load reduction, porous shape, latent hydraulicity, high internal friction angle, uniform particle size, safety *For more details, please refer to the PDF materials or external link pages, or feel free to contact us.

Technical basis for the permeability coefficient of permeable paving material "Color Sand"

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

This document explains the technical basis for the permeability coefficient in "permeable blast furnace slag pavement (colored sand)." Our paving materials use granulated blast furnace slag as a raw material, which falls under the classification of sand and gravel. Therefore, we conducted the "constant head permeability test" to measure the permeability coefficient. The result of the constant head permeability test showed a measured value of 2.56×0.01 cm/sec. Thus, the required permeability coefficient for the sidewalk area in terms of "permeability" is a public standard value of 1.0×0.01 cm/sec. Our material exceeds this standard value by more than double, proving that it sufficiently meets the permeability performance required for sidewalk areas. [Overview] ■ The permeability coefficient was measured in accordance with the "Soil Permeability Testing Method" based on JISA1218. - Constant head permeability test... Applied to soils with relatively high permeability coefficients (sand and gravel). - Falling head permeability test... Applied to soils with relatively low permeability coefficients (clay, silt, etc.). ◎ Exceeds the standard value and sufficiently meets the permeability performance required for sidewalk areas. *For more details, please refer to the PDF document or external link page, or feel free to contact us.
