UG-Mat Coal Bottom Ash/Boiler Slag | Recycled Materials ...
Particle Size Distribution: Bottom ash is a well-graded material with particles ranging in size from fine gravel to fine sand with low percentages of silt-clay sized particles. Bottom ash is predominantly sand-sized, usually with 50 to 90 percent passing the No. 4 sieve (4.75 mm) and 0 to 10 percent passing the No. 200 sieve (0.075 mm).
