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.
