fine aggregate used for this comparative study are sand as available and bottom ash as available. BOTTOM ASH Bottom ash is formed when ash adheres as hot particles to the boiler walls, agglomerates and then falls to the base of the furnace at a temperature around 1200 0C (Kim et al., 2006). Hence the term “Bottom Ash” is coarse, with

Choosing the Right Blast Media for Abrasive Blasting
A fine abrasive will give you more impacts per volume. The more particles in the stream, the more work is accomplished in the same time. When blasting concrete or wood, you don’t need a hard, expensive abrasive, or a coarse particle: crushed glass makes an excellent, inexpensive choice for work on relatively soft surfaces.
