Abstract
A fiber-reinforced concrete-like material product includes a plurality of fibers containing an effective amount of at least one antimicrobial agent to inhibit organisms and protect the concrete from biological attack. Preferably, the antimicrobial agents are added to the fibers prior to the fibers being dispersed in the concrete. Such a concrete product containing antimicrobial-enhanced fibers simultaneously inhibits organisms from biological attack, reduces plastic shrinkage cracking of the concrete and improve post-peak flexural strength of the concrete.
Claims12
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.
A method for inhibiting organisms throughout a concrete product comprising the steps of:
- distributing a plurality of fibers throughout the concrete product during the formation of the concrete product, as least one antimicrobial agent being combined with said fibers prior to the distribution of said fibers throughout the concrete product and being dispersed throughout the concrete product by said fibers.
A method for simultaneously inhibiting organisms throughout and closely surrounding a concrete product, reducing plastic shrinkage cracking of the concrete product, and improving post-peak flexural strength of the concrete product comprising:
- blending a plurality of fibers with concrete during formation of the concrete product, at least one antimicrobial agent being combined with said fibers prior to blending said fibers with said concrete and being dispersed throughout the concrete product by said fibers.
