Silex is any of various forms of ground stone. In modern contexts the word refers to a finely ground, nearly pure form of silica or silicate. We at Silex Group prefer to think of Silex as Recycled Concrete Aggregate (RAS).

Origin of SILEX

In circa 1590, as a Renaissance —Early Modern Era term in Latin, it meant powdered or ground up "flints" (i.e. stones, generally meaning the class of "Hard Rocks")
