摘要
PURPOSE: Antifreeze materials having heat insulation and lightweight are provided to prevent road from freezing, improve paving efficiency, and reduce pollution and disposal costs by using granite, styrofoam and cement as raw materials. CONSTITUTION: The antifreeze materials applied to the bottom of road, rail road and airport are produced by mixing 79.9-88.8wt.% of granite powder as a main material, 0.1-2.0wt.% of waste styrofoam pieces with a size of 0.5-2mm, and 10-20wt.% of cement, wherein the maximum drying density of the mixture(antifreeze materials) is 95% or more.
