Cement reinforcement Gale, D. M. (E. I. Du Pont de Nemours and Company, Wilmington, DE, USA) US Pat 4
September 1987) A method of reinforcing a selected portion of the walls of a structural member is described. Macrospheres, composed of bondedtogether microspheres (3-9mm in diameter), are coated with an adhesive in such a manner that they will bond with adjacent macrospheres and yet leave voids between them. The macrospheres are then closely packed into the structural member at the selected portion so that they will engage with one another and with the walls of the structural member. Curing the adhesive achieves bonding between the macrospheres and the walls but airflow is permitted through the voids.
