Appeal No. 1997-2071
Application No. 08/336,529
According to appellant, the invention is directed to a
method for inhibiting organisms throughout a concrete product,
and the resultant product, by introducing an antimicrobial
agent into a plurality of fibers before the fibers are blended
with the concrete to form a reinforced concrete product
(Brief, page 2). Claims 1 and 18 are illustrative of the
subject matter on appeal and are reproduced below:
1. A reinforced concrete product comprising:
concrete; and
a plurality of fibers, said fibers individually
including an effective amount of at least one
antimicrobial agent and uniformly dispersing said
antimicrobial agent throughout the concrete product to
inhibit organisms therein.
18. A method for inhibiting organisms throughout a concrete
product comprising the steps of:
introducing at least one antimicrobial agent to a
plurality of fibers; and
subsequently distributing said fibers throughout the
concrete product during formation of the concrete
product, thereby uniformly dispersing said antimicrobial
agent throughout said the concrete product.
