I am a scientific research from Inasmet, R&D Center of Spain. I would like to ask about possible uses of a by-product coming from the granite cutting industry. The characteristics of the product are the following:

• This product is an sludge of grey color (It contains about 22% humidity) thatcomes from cutting of big granite blocks. If necessary, material can be dried.
• The composition of the dry product is 65% silica, 13% alumina, 6% calcium oxide, 7% iron oxide (III), 1% magnesium oxide, 3.5% potassium oxide and 2.5% sodium oxide.
• The particle size is about 0.12 mm.

Could you tell us if there are any applications for this material or any uses of it in different countries?

Thank you very much in advance.
