If portland cement can be formulated with nano-size cement particles, it will open up a
large number of opportunities. For example, the cement can be used as an inorganic
adhesive with carbon fibers. Currently the micron size cement particles are not conducive
for use with 7 micron diameter carbon fibers. The cement will not only be more
economical than organic polymers but also will be fire resistant. In addition it will not
emit any volatile organic compounds (voc) and the composites can be attached to parent
concrete substrate using a compatible adhesive. It will be also very competitive with
current inorganic composites because they have to be processed at high temperature.
