Abstract
A free aggregate usable in forming wood concrete products is formed by a process including the encasing of a free aggregate of individual chips with an inorganic mineralizing coating to a degree sufficient to seal in water-soluble organic matter held in pores of the chips, while maintaining the individual chips in a free aggregate form. The encased chips are then seasoned for 15 to 25 days and again coated with a second mineralizing coating.
Claims3

- and
- a two layer kaolin mineralizing coating encasing the individual chips to a degree sufficient to seal in water-soluble organic matter held in the pores of said chips and prevent the leaching thereof, while maintaining said individual chips in a free aggregate form.
