ISF anti-skid surface coating

Anti-skid coatings (ASC) refer to a surface treatment of roads by providing improved top surface skid resistance. Normally the thickness of the coating is about 3-5 mm and helps drivers brake under emergency conditions at hazardous locations. Ordinary ASC contains natural bauxite as an aggregate for surfaces subjected to high friction. Although there is an increasing interest in ASC, natural bauxite stops the development of such coatings, because of its very high price and rarity. Iron-silicate fines (ISF) can substitute natural bauxite in ASC and make geopolymer concrete with better properties. The Polished Stone Value (PSV) is a coefficient which defines road resistance to skidding. ISF improve the PSV value and the abrasion resistance of synthetic geopolymer in general. University of Ulster, Northern Ireland are responsible for current research and development of ISF ASC, according to EN and ASTM standards.   


There are several benefits of ISF valorization in anti-skid surface coating:

» Improved abrasion resistance;

» Improved compressive strength;

» Certified building material according to EN 12620;

» Sustainable building material.
