Germany leads the pack with the largest number of ...
Nov 01, 1976· ASTM C 33, "Standard Specification for Concrete Aggregates," permits a maximum of 0.5 percent lignite in aggregate used in flatwork or other concrete where surface appearance is important. (For other concrete as much as 1.0 percent is permissible.)
Apr 01, 2004· At first you'll be able to see the small, dark lignite remaining at the bottom of the pop outs. But because it is relatively soft, it will soon wash away. There is a standard limiting the amount of acceptable lignite in fine aggregate, ASTM C33, "Standard Specification for Concrete Aggregates."
